Relative newbie here to layers in PSE 2 (Windows XP).

I followed the directions precisely on how to create a simple drop shadow on a photo. At a certain point in the tutorial, after you're prompted to "make this background a layer", you're instructed to increase the canvas size height and width to 115%. You're left with a very nice drop shadow but also excess white canvas that gets saved with the new image.

There's got to be a quick, easy way to get rid of that excess canvas and isolate just the image with the drop shadow, but I haven't been able to figure it out after much trial and error, following the drop shadow posts here and numerous web searches. A simple crop obviously is much too coarse and will leave snippets of the white canvas remaining.

A quick "point-by-point" mini-tutorial would be greatly appreciated, thanks!
