Can the gallery itself not be re-sized to fit a 760 wrapper? You are correct that trying to change the outterwrapper size leads to a whole set of new problems. I tried resizing the images as per another post, going to admin_gallery/common/properties.php and changing the 1024 array size to a 680x420 size and then changing the watermark to force a re-size but this had no effect. The images did not re-size. I must be misunderstanding the process. Considering your sitebuilder uses a 760 outterwrapper size it would make sense that the gallery could fit in this framework.
