Ok I tried to make my rainbow smaller but it didnt work ???? help !!!
Sorry Trace, my directions ^ were just for text signatures (like how mine says "I could give up chocolate but I am not a quitter").
Your rainbow image is hosted at photobucket. I am not sure if you can edit your images at photobucket. The other alternative is to edit the image size on your computer (using paint or photoshop) or an online editing site (like shrinkpictures) and then upload your newer, smaller image to photobucket and link to it via your signature.
The dimensions for the allowable or recommended size is in this thread, but from memory they are 100 pixels high, 400wide. Yours is currently 374px high × 182px wide.
