In order for your custom Twitter background to be viewable by most browser/screen resolution combinations, you should plan on using a width of 41 to 108 pixels for the important stuff. The photo on my background is 200 pixels wide.
Not sure yet whether I’m going to just shrink down my existing photo and text, or do a complete redesign. I’ll have to do one for the Total Rottweiler Magazine Twitter page as well. Adding to the to-do list now!
