Video: Image maps

In this last movie of this chapter, I'd like to take a look at one more type of linking called "image maps". I'm going to go ahead, and close this document that we were working on in the previous movie, and in my Files panel, we're going to open up a file called "locations.html". And this is just a page that will direct people to the different teacloud stores located all over the country; so easy to set them up when you have a fake company. But what we have here is an image of the United States, and you can see it's divided into pacific, northern, eastern, and, southern areas. Now, this is one image. You can see there's a box around this entire image.

Image maps

In this last movie of this chapter, I'd like to take a look at one more type of linking called "image maps". I'm going to go ahead, and close this document that we were working on in the previous movie, and in my Files panel, we're going to open up a file called "locations.html". And this is just a page that will direct people to the different teacloud stores located all over the country; so easy to set them up when you have a fake company. But what we have here is an image of the United States, and you can see it's divided into pacific, northern, eastern, and, southern areas. Now, this is one image. You can see there's a box around this entire image.

If I wanted to create a link to my stores, I can only have one link when I have the entire image selected like this. Notice down here with this image selected, I have one Link field just like when I had these Menu buttons selected up here; I have one link field to set links for those Menu buttons. But there may be times when you want different areas of the image to link to different parts of your web page. In order to do so, you need to create an image map, in which you actually map out regions on the image to provide links to other web pages, whether they happen to be on your site, or otherwise. Notice with this image selected, we have this Map area down here in our Properties Inspector.

If you don't see that area make sure that your Properties Inspector is not collapsed like this. Make sure you have the full Properties Inspector available, but you should see this Map area down here. And the Map area basically involves these four tools that you see here. We've got our Pointer Tool, which is selected by default. A Rectangular Hotspot Tool, a Circular Hotspot Tool, they call it the Oval, but you can only draw circles with it, and a Polygon Hotspot Tool for drawing irregular shapes. And basically you use these tools to draw the areas on your page that you want to turn into Hotspots on your image map.

Now, for something as irregular as the United States is shaped, I'll most likely want to stick to the Polygon Tool. Maybe I could get away with the Rectangular Tool up here for the northern stores so, if select the Rectangular Tool, and I'm just going to put my curser right here at the border, drag up, and we'll just take it to right there. We'll leave out that little piece of Michigan for now, and there is my Map. Notice this message that I'm getting that says "Please describe the image map in the 'alt' field on the Properties Inspector". This description is going to help visually impaired people who use tools that use the web. Basically people with vision disabilities, who might have audible readers, or screen reading software to read their images, they won't be able to use your image map unless you provide this alternate text for accessibilities reasons. So, you can see, with my image map drawn, I have a Hotspot Properties Inspector now, and right down here I'm just going to type in "northern stores" as my alternate text, that way there'll be a description of what this box is.

Notice that we have a link area that automatically has a "#" in there. Right now it's just a placeholder. What you need to do here is actually just link to the web page that you want to link to. So, If I in fact had a page listing all the stores in the Northern United States, I could link to that page, just by browsing for it, or pointing to the file, or just typing it in. I don't have any of those pages created right now, but just for this example we'll just imagine the page is called "northernstores.html", and that's it. That's my hotspot link. If I save this page, and check this out in the browser. Here's my page. Notice that as I roll over the image, I don't see a pointer finger until I roll over that area where my image map exists.

There's my link area, and if you look down here at the Status bar, you can see that it's linking to northernstores.html. Of course, that page doesn't exist so, it's going to tell me it can't find it, but you got the idea. I've now drawn a hotspot on this image, and that's the only part of this image that's currently active as a link. Back in {italic}Dreamweaver,{plain} if I go look at the code, you can see the code that it actually had to write for this. It writes coordinates, as you can see right here describing that area. The shape is a rectangle, those are the coordinates, and there's the link. Now, the rest of these areas I probably cannot get away with using the rectangle with. So, instead I'm going to come down here, select the entire image first, come down, we're going to get the Polygon Hotspot Tool. The Polygon Hotspot Tool allows you to draw irregular shapes, and the way that it works is you basically click your points around the area that you want to turn into a hotspot.

Let's just stay we start right down here, and I'm going to click once. It's going to give me a message again. I'm just going to say OK, and dismiss it, and then we'll just come in here, and notice that it's drawing lines. When I click my third point, {italic}Dreamweaver{plain} tries to close off the shape. I'm going to ignore that, and just keep clicking around the pacific store area here. It's best to try to use as few points as possible, meaning there'll be less code written. You don't have to be exactly precise along the entire edge of the United States here. And let's see, that's probably good. Now, obviously you don't want to overlap other hotspots or else you'll have some kind of weird conflict going on with the same area linking to two different spots.

So, avoid overlapping your hotspots. It looks like I didn't quite line that up the way I wanted. So, what I can do is select my Arrow Tool now, and now I can click on a point and I can edit that point and change it so, let's make sure that lines up a little bit better to the northern stores area. Maybe like that, just drag that up a little bit more, and maybe we'll just drag that so the actual bowl is included there. And there's my irregular Polygon Hotspot shape. We want to make sure that we add some alternate text.

And we'll add our non-existent link. Of course, I can always create these pages later, and my links will already be created. So, there it is, and I can now work on my next hotspot. Now one thing to be careful about when working with the Polygon Tool, because you're working with an irregular shape, {italic}Dreamweaver{plain} has no idea when you're done drawing that shape. So, if I come in here, and select the Polygon Tool again, with the pacific stores shape still selected, if I start clicking it's going to assume that I want to continue working on that shape. Let me undo that. So, what you need to do is after you draw your shape, if it still has these dots around it, these handles around it, {italic}Dreamweaver{plain} assumes that you still want to work with that particular hotspot even if you're done with it. So what you want to do after you're done is make sure you select the Arrow Tool, click somewhere off of that shape to deselect it, then select your Polygon Tool again, and then you can start drawing a new shape, and we'll just come in here, and ignore that, and we'll come in here, and continue clicking around to draw our next shape. And again just try to use as few points as possible, and just get the general shape of the hotspot you're trying to draw. Just like that, and we'll call this one southern states.

Add our link, and to draw the last one, again we want to select the Arrow Tool, click off to deselect that shape, select my Polygon Tool again, and now we can come in here, and draw the next shape, and there we go.

We'll call this one "eastern stores", and we'll add our link, and there it is. So, now I have my four Hotspot areas. Now, I guess I called that one "southernstates" by accident. Let's change that back to "stores". The thing about the Polygon Tool is that it's a lot more complicated to write in code.

You see, compared to the rectangle, which had four coordinates up here, this Polygon has a lot more coordinates. So, just be glad that {italic}Dreamweaver{plain} does all this for you, and you don't have to map this out by hand like we used to have to do when created image maps. So, now if I Preview this in my browser, if you watch the Status bar down here at the bottom as I roll over these different areas, you can see that even though I have one image, I've created four different Hotspots that link to four separate pages in my website. So, that's creating an image map. Now, incidentally if you don't want to see that message that appears every time you try and draw a hotspot, if you get the idea and just think you'll remember that you have to put in some alternate text, what you can do-- Let me undo that spot I just put down.

Go to {italic}Dreamweaver{plain} Preferences, and under the Accessibility category you can uncheck Images from the Show attributes when inserting, click on OK, and now when I draw a hotspot I don't get that warning, and I can just draw my hotspot under interrupted. I'll just delete that. Just be aware that when you turn that off you will no longer see the dialog box when you drag in images as well, so remember that alternate text is important but if you don't want to see that reminder every time, you know how to turn that off now. So, that's how we create image maps in {italic}Dreamweaver.{plain}
