I'm not sure if I quite understand your problem- sorry- but are you saying that the image you use keeps repeating as you scroll down and when it repeats at some point it looks cut off? If that's the case, I would recommend putting a table on your page, make it 100% width and height. But the image as a background in the table but then in the table properties set backround to not repeating.
I used a picture publisher to make a unique background 640x480, but when loaded in FP it repeats and breaks up page....tryed also making own buttons in other program but soon as I load in FP you only see part of it...what am I doing wrong? driving me nuts, tryed to make pixels larger, still same issue...Help Thanks
