I have this functioning much better now mostly thanks to Jesse Pinho who sent me his script of basically the same. A few mods and it worked horizontally as I needed.
Seems to work well in FF. It functions in IE 7.0.x but always displays (xx items remaing) in the status bar and appears to be loading the images constantly. Looking for some solution to this... Thanks,Adrian example: http://www.ezfoamglove.com/dev/scroll_gallery.cfm @Rick Faircloth: thanks for pointing that out, its much better without the mouseover.
