Hello Bethofvt -
When you have completed your upload, are you then checking the Image Management area of your account to ensure whether or not the images have uploaded to your account? It may be a result of your account settings if you are having difficulty adding the images to listings but the images are actually uploading to your account. In order to be sure of what may be occurring for you, we would need to look in to your account specifically, and check the settings - and do some troubleshooting if the images are not being uploaded at all. In this case, I suggest that you file a support case from under the Help tab of your account letting us know what occurs when you try using the uploader as well as what browser and Operating System you use and we'll be happy to help sort it out.
