I am using this on my site and it's great. I am using Medhi's Coppermine Bridge and it works perfectly with that. I would imagine that it works with the others as well because it's very configurable. There are two minor issues I would take with it, but other than that, it's perfect.

First "problem": It uses the tag, which appears not to be supported by Firefox but instead of showing a small, scrolling module in Firefox, it shows the whole list of 10 images. Thus the module is pretty (in space on the page) large in Firefox. However, I have it at the bottom of the right side of my homepage, which is a reasonably large page anyway, so this is not a problem for me (and I doubt it will be for most people), it looks good either way, I may even prefer the way it looks in Firefox :-D

Second "problem": When you click a thumbnail in the list, it opens the image in full-size in a pop-up window, where I would prefer to have my users redirected to the image's page in the gallery so they can comment/rate it and browse the album.

"Fix": I used this fix for the second issue.
1. Get it working as described in "problem 2" above
2. open joomla/modules/mod_cpgscroller.php
3. Around line 98, find:
echo "filepath$row->filename\" TARGET=\"content\">";
4. Replace this with:
echo "pid\" TARGET=\"_self\">";

This worked for me :-)

I would definately advise this for anyone using Coppermine in Joomla.

I tried about 10 different gallery solutions before settling on this one. I was pretty disapointed with all the others (except G2 which was very good). The others either were not feature rich enough / too basic / not very good looking or buggy.

The G2 bridge didn't want to work with my phpBB2 bridge login at all but with two little adjustments, Coppermine worked fine! (I simply edited the links for logging in and out in coppermine so they redirected to the forum for login log out, once users logged in out through Joomla/forum everything worked fine).

I also found editing the Coppermine skin easy (despite being a newbie) to make fit with some of the rest of my site.

Coppermine was built from the ground up to be integrated with forums and CMSs like Joomla which is probably a lot of what makes this integration as tight as a bass drum! 5 stars!

This is a great component once you get it working. I was mostly inexperienced in PHP and MySQl and after a few easy adjustments I got it running smoothly. There is good support from Joomlastuff.org too. I'm actually use this in my Joomla site. 4 stars.
