Video: Using the Slice tool in Photoshop

In the exercise files, let's open the flags.psd up in Photoshop. You will find that file inside of the Art Templates folder. Let me zoom up here. So what I want to do here is create slices to slice out the individual flags from this larger canvas. Under the Cropping tool, click and hold, and let's come down and get the Slice tool. Let's click and drag a slice over the flag of England. We will name this 'england' and every one of our flags will be 20 pixels wide by 13 pixels high. Let's click OK.

Draw a slice around Canada, type in 'canada' for the name, click OK, italy, double-click, click OK, and lastly let's double-click on usa, click OK. Now if my slice is created, let's choose File > Save for Web & Devices. Let me zoom up here. In the left-hand column here, in the Save for Web & Devices dialog box, I am going to come down and make sure Slice is selected.

I can click on each slice and see the JPEG settings for each one of these. Each one is set to 80% Quality. Let's click Save. Next, I am going to come down to the Settings. Let's choose Other. And under the File Savings panel here, we are going to type in 'flag_' at the beginning of file naming, so every flag will be named with flag_, and then the slice name, and then finally the file extension at the bottom. Choose OK. Under Slices, we are going to say All User Slices, so any slice we created will actually be saved out.

Let's go to the desktop/myMarquee/ images/template and then hit Save. If I come back to the operating system back to the folders we set, we can see now that we have an individual flag for each one of these, canada, england, italy, and usa. Let's come back to our source Photoshop file. Let's close, Command+W or Ctl+W, and then hit Save to save your file, and in the next movie we are going to set up the marquee caption background graphic inside of Illustrator.
