Jizz, don't know if it'll help, but I've just used the right-click and copy of the thumbnails from my website.
Paste them into a blank picture with Photo Editor (comes free with Offic 2000).
Crop it down, and then open with Paint to add some text, and what have you.
At the moment, I havent added text this time around, just text from the Sig Editor on here.
