Hi Judy,
I know exactly what each tag does and can "imagine" what the result will be from use. The IMAGEx_ORG tags literally insert the full-size original image you upload, so a "parade" of possibly 1024x768 pictures comes immediately to mind. If that's the issue and you like Auctiva's more "Standard" images with supersize, etc., that simple replacement I suggested should do the job. With that universal tag, you get the flexibility of placement of the images and the method as selections in the one-page lister when you select your Custom template (it's on that pop-up screen at left).
