The THUMBNAIL that is used throughout SC for a particular Item is the 1st Attachment for that item. Images embded into the body of one of the content tabs will only be displayed in that tab. You will notice that your item doesn't show up on the Home Page because it doesn't have at least 1 attachment to it. You will also notice on the Category pages, it lists your Avatar instead of a thumbnail for the item. I did this on purpose for SC Items without attachments.

btw, I moved this to technical support since its a functionality issue and not something that you can even request as a feature.
