[syllogism]

I was told not to write HELP in the Subject Area. So here goes HELP!
I am using Flexy Rectangles which has a photo (main_bg_1.jpg 1000 x 132). If my monitor setting is 1024 x 768 then I see only 70% (approx) of photo. If the setting is 800 x 600 then I see even less and with 1280 x 1024 then I see everything. I need a simple solution that will accomodate a customer regardless of his/her monitor setting. I suspect the solution may require that I create 3 images (which is fine) but I need to know the IF/ELSE logic that will recognize the monitor setting.

If anyone can help I would be most appreciative.
