My knowledge of photoshop isn't bad. Though I'm not an expert (yet?). This particular issue has me a bit stumped. I'm familiar with alpha channels, but not sure how to get a partially transparent object from a solid background.

I want to get a picture with it's transparency preserved. but I can't get it directly. The best I can do is take a screenshot of it on a colored background. Cutting it out would be pretty easy, but that alone wouldn't preserve it's transparency.

The particular image is this:

it's a nametag, partially transparent. Shown with a white background, but I can get a different color if it would make things easier. I need a way to filter out the white background, and get the nametag on a transparent background. Any advice?
