Hi Karen,
Welcome to Auctiva! I just reviewed your account and found that the reason many of your store window images are not loading is because the Auctiva store/store window images for these listings were not created when they were imported into your Auctiva account, which typically happens automatically. I have just initiated a command to create these missing images and you should be able to see the results within about 30 minutes.
Your active listings do not necessarily show up on the "Create from Similar" list and on your saved listings page. We just create saved listings based on 5 of your imported listings upon sign up. Once your listings close, they will be displayed within your Auctiva account on your Closed Listings page. From there, you can created saved listings from your closed listings by checking the boxes next to the desired listings, and clicking the "Import Listings" button. Once you have done that, the selected listings will appear in your saved listings folder within several minutes, from where you will be able to easily edit and/or repost these listings.
If you have any additional questions or concerns, please file a support case using the appropriate link on our help page:
