-To find images that have been cropped from others,…we need to loop through the thumbnails,…and pass them in pairs to the find sub-image…function that was described in the previous video.…I'm back in the main script in find underscore…cropped dot php, and we need to include…that function definition.…So at the top of the page, require once.…It's includes sub-image underscore search…dot php, and the rest of the code needs to go…down at the bottom of the page, just…before this end micro-time.…
So let's add in a few lines, give ourselves…a little bit of space, and when we find a…sub-image, I'm going to store its details…in a multi-dimensional array.…I'll initialize that now.…So that'll be called pirated,…and because it's a multi-dimensional array,…I need a counter.…I'll call that P and initialize it to zero.…Each time we loop through the thumbnails,…I'm going to remove an image from the…re-sized array, and use it as a reference…to compare other images against.…
So we'll have a while loop and the condition…will be count and re-sized greater than one.…
