Reduce size of an image

Hi,

I made a 5x35 image using a gradient that i'll use as background for a div. I saved it as .jpg. Its size now is 325 bytes. Is there any additional method to make the size smaller?

Thank you

325 bytes is already in the trivial size range... This said, you should be using PNG, a much better format for Web graphics outside of photos. In this format a 5*35 gradient image in 212 bytes, but you can likely reduce it to 1*35 (157 bytes)

And pngcrush might be able to shave off a few bytes afterward - I've gotten mixed results myself, but if bandwidth is a huge concern it may be worth a try.

After pngcrush, also process the image with AdvPNG (which is much faster, and sometimes achieves better compression than pngcrush) and PNGOUT but only
if you have a lot of time) .
