Hello all!

Does anyone know good and fast thumbnail script?
I have trying many thumbnail functions and scripts and none of them are:
- fast enough
- Doesn't do what it should
- Is too complicated

Perfect script for me would be:
- What rename files
- Support for .gif .jpeg .png .bmp
- easy to use.. Function would be the best!

Before you post "Do it yourself" .. Well, I have try many times, but my skills just aren't that good! (yet) :(
I would use this in site where member is uploading picture, script is generating 3 versions of it. Small thumbnail (80x80), preview thumbnail (150x150) and view image (640x480) and uploading those own folder.

Thanks for all help - Marxx
