I'm writing a simple gallery plugin for my site, and while I have the basics of what I need to do down, how do I call on an image thumbnail if it's not the featured image of a post?
Essentially (since I'm only using this on my site), I want to feature the thumbnails, in order using a loop, of image1.jpg, image2.jpg... you get the idea. But I want to call on the thumbnails of http://mysite.com/wp-content/uploads/image1.jpg and so on.
