I'm trying to move from 184.108.40.206 to 3.0 by setting up a test site and getting familiar with all the changes. Using the default theme, there are two thumbnails beside the product options. Code inspector says the images are from the cache and are no_image-50x50.jpg. This would imply that the options themselves can have an image and mine don't. Is that true. If so, where to you put an image with options. If not, why are the thumbnails there? Screen section attached as image.

Did you copy all the data (images, thumbnail) from your previous site? Missing image is a default thumbnail that shows up when original image not found. So you better copy your image folder here so that all missing images can be recovered. Hope Helps.
