Hi Ramon,
Thanks for posting your question here. All Auctiva hosted images will continue to be available in active eBay listings while our scheduled maintenance is in progress so you should not need to move any of your images over to eBay's image hosting service. It just will not be possible to upload new images during that time because our site will be inaccessible.
I hope this helps. If you need any further assistance with your account, please feel free to contact us by mousing over the "Help" tab and selecting the "File Support Case" option.
-Mike
