After looking at the beautiful siggies I thought I would try my hand at it. I looked at the sizes, 550 x 134 pixels at 72 pixels/inch, I fiddled with the background until the file size on my computer was only 28 kB, I upload it to photbucket, where it shows up as being 24 kB, but when I try to upload it to thecatsite, it ends up 34 kB? I don't want to just resize it, I would like to understand why it is being a byte pig.
I see other siggies with the same dimensions and they have much fewer bytes.
