Transparency on Stretched Background

Not much explanation needed: transparent .png on a stretched background produces a square of the unstretched background around the .png. It's the Alpha channel thing, but what do you do to work around it?

I searched the forum for this as I presume it's been asked before. Also not sure if it's a graphics question or a web design question.

Yes, I still need to clean up around the chunks of soy/meat
