[dannyboyd]

I have made the coppermine accessible for everyone and guests can open the video i have form a link. But there is a problem using the block pcCPG/Show random images block that links to the pics and videoes from the front page on the site.

Then it makes a white page with this adress - error

Guests/anonymous have read access to coppermine
I have tryed to add permissons to teh guest group to test - and also looked at the rights i chmod - but its´ full aceess. but still a problem ?

site http://www.vaerkstedshuset.dk - Click on the link under the pics  - name "Billedalbum" link

Now I have changed the file belonging to that module with a standard html link directly to the album and pics. in the top - Billedalbum / Videoalbum - and it work fine.
