If after installing WooThumbs your single product page layout is messed up, you may need to change the width of the images display. Let me show you how:
By default, WooThumbs is set to be displayed at 48% width. This usually accommodates most themes, but in some cases it just doesn’t look right.
To change the width of your images, navigate to the WooThumbs settings panel. Under
Display Settings, find the
Width (%) field. If your product summary/description is below your images, try decreasing that value. If your images are not wide enough, try increasing it.
