I finally moved my cover collection to a new and reliable host. I also added a simple upload section, where you can upload your covers (jpg < 2500 Kb) for temporary hosting.
From time to time I will move covers from the upload area to the gallery, if the creator has no objection. Of course I have to take the upload section down if there are too many abuses.
