To upgrade your product more information page template from using the regular product more information page graphic and only that graphic to using that image PLUS up to 20 resized images of that product is as easy as replacing a single tag. In your product more information page template, where you would normally put the more information page graphic tag [-- PRODUCT.MoreInformationGraphic --] put the multiple image tag there instead, [-- MoreInfoImageRow --]. The regular product more information graphic function will work as it always has, but now if the merchant has setup additional images those images will be displayed as thumbnails and will be regular size when you hover over them.
The resulting code will look similar to:
This feature does use the resized image feature, so you will want to make sure that you go to Images > Configure, to set that up. You will also want to go to Preferences > More Info Pages, and set the image roll over settings including the size of the main image area, and the number of images per row.
Advanced - If you would like to have even more control of the images and how they are displayed you can use the regular product more information graphic tag, as well as the tag below to directly access the additional product images.
