Hi Texas Skipper,
If the images embedded in the html are hosted on the web, the should show up so for further assistance with this matter, I recommend filing a support case using the appropriate link on our help page:
http://www.auctiva.com/free_auction_software_help/help.aspx
You can also place images directly into the description using Auctiva's editor. There is a button on the editor tool bar with an icon of a mountain and sun on it that can be used to insert images directly in the description.
