Hi grannyjan,
The images in your listings will not just disappear simply because you relisted them through eBay. They would only disappear if you deleted the images in those listings from your Auctiva account and they are now in your Deleted Images folder. If there are no images in your Deleted Images folder, none of your images will disappear unless you go in and delete some images.
The reason that some people who relisted items through eBay are seeing their images disappear is because it has not been fully understood in some cases that our image deletion wizard and the other tools on our image management page that operate based on whether images are being used in active listings will only recognize the association between an image and an active listing if the active listings are direct posts/relists through Auctiva.
As a result, some users who have used our image management tools to delete all their images that are not being used in active listings have ended up deleting images that were being used in active listings because those active listings were relists of items with Auctiva hosted images that were done through eBay and therefore our system did not recognize that the images in them were being used in active listings.
I hope this helps.
