how do i make them download th epic instead of right clicking and finding my properties. also how do i only let registered users view normal pic size and unregistered users see just the thumnail?
1) only one question per thread (you agreed on respecting this policy when you signed up for your account on this forum) ::)
2) It's in the nature of the www that people can find out the location of your pics by looking up the properties (with right-click or other methods), there's little you can do against this. If you're afraid people will steal your pics, don't publish them on the internet in the first place. You could try using a no-right-click script (not recommended though, as there are other methods of stealing pics), or add a watermark to your images (preferably before upload). This has been discussed already (both on this forum and elsewhere on the net), use the search (http://forum.coppermine-gallery.net/index.php?action=search) or google.
3) Refer to the FAQ (http://coppermine.sourceforge.net/faq.php) for your second question
