Thread: Starting a Slideshow Program... Lost

I'm trying to get started on a slideshow program, but I'm stuck trying to print an image to the canvas I've created. Any help would be appreciated. I know its sloppy now. I'm kind of new at this. The problem seems to be between lines 321 and 338 in the getBrowseAction method.

Yikes, that's way too much code to sift through. Get your problem boiled down to an SSCCE, and we'll go from there.
