Hi Jaytee28,
If you log into your Auctiva account and go to
https://www.auctiva.com/listings/upload.aspx you'll see the step by step instructions to help you upload your listings & their images into Auctiva using the Turbo Lister File Exchange Format. You'll simply need to export your listings from eBay's Turbo Lister app in the File Exchange Format, then in the CSV file, you can enter in your image URL in the column with the header "PicURL".
Sincerely,
Natasha
