What sort of graphics you need I create a few images for my site.
I got the coding side of things down, but never really was any good at the graphics side.
Would be great if you could make some twitter signature image backgrounds.
I setup a script that generates twitter signature by taking a background and adding the users twitter picture and last tweet on top of the image.
link to the generated signature image is
http://mikestoolz.com/twit/sig.php?name=mikestoolz
just replace mikestoolz on the end with your twitter name.
background image size is 400X54
and should be PNG format.
I know some graphics tend to use a shine or gloss so if that is something you want to be part of the image, just create a seperate image with just the gloss or whatever and i can sett it to go over the top of the packground after adding the user pic and tweet.
The signatures created are free to be used by anyone as I have unlimited bandwidth.
Any one who wants to create a background feal free to make it and ill add it to be usable.
