Hi,
You can actually use HTML to resize the picture without having to create resized versions for test.
Locate this statement in the code:
<IMG src="http://i681.photobucket.com/albums/vv176/lavaliere/abheader-1.jpg" width=950 height=204>
Remove the height=204 and change width=950 to width=850 to test the picture at that width, so the statement becomes this...
<IMG src="http://i681.photobucket.com/albums/vv176/lavaliere/abheader-1.jpg" width=850>
Removing height and adjusting width will cause a resize without stretching/changing aspect ratio of the picture.
If 850 isn't small enough, try smaller. The scrollbar at bottom should give you clues if you're getting close. Set your monitor to 1024 x 768 resolution, so you'll know if your getting the scrollbar at that minimum setting for final checks on revised listing.
