This is impossible, once you display a picture on internet with a flash movie, you can't protect it from being directly accessed.

The secured content in UMG module is the "Download", the download could be large resolution picture, media files, etc. the users can't find the url to get the download.

Thanks.

Happy new year :)

Thanks for your suggestions, but currently I'm not working on this issue, I think it may be unnecessary to protect these display pictures which can be easily copied with a screenshot. don't you use the "link as download" feature?

Thanks.
