Hello Choppsshop -
If you are having difficulty with the new uploader, we can very likely assist you with it. All you would need to do is file a support case from under the Help tab of the site letting us know what you have been encountering with it and at what point in the process you have trouble and we would be happy to look into it for you.
If you do wish to delete you images, that would prevent them from being visible on eBay in listings that user Auctiva hosted images. However, if you close your account, the images should remain available on eBay for such listings. We do reserve the right to delete images from an account any time after 14 days have passed after it closes, but they will remain available on eBay at least for that time.
Please feel free to let us know in a support case what occurs for you with the uploader and the difficulty you are experiencing and we can take a look into it for you.
