Here at renderosity thumbs must be less than 15k, Ive been tring to make this thumb less than 15k in .jpg format but it looses a LOT of definition as you can see. Ive never had this problem before so I dont know what happens now... please do you know what can I do? Thanks a lot ;-)

Since you have sharply defined color contrasts with only a few colors, try a gif instead. Jpgs tend to create artifacts at the edges of highly-contrasted colors like that. Also, make sure you reduce the size (pixel dimensions) of the original pic before you save as either gif or jpg in order to keep the crispness intact. Hope this tip helps.

Yes thanks a lot! ;-)

As long as your thumbnail is less than the 200x200 pixel limit it should upload even if it's over 15k.

imageready does a better job with jpgs than photoshop, try that.
