I am using Coppermine gallery and joomla and when I push the previous/next arrows to change the photo I loose the position reached by vertical scroll in and my page came back to the top. Here http://www.pedalecesenate.altervista.org/sito/gallery/displayimage.php?album=7&pos=0 you can see this disappointing behaviour while here http://www.diocesidiiglesias.it/sito/index.php?option=com_wrapper&Itemid=76 you can see the desired one; how can I get it?
You better ask this on the Joomla boards. We have no idea how the visual integration of Coppermine into Joomla actually works. The bridges we provide only take care of logical integration in terms of user management. Visual integration is nothing we could provide, simply because we don't know nor use Joomla.
What you're talking about is an "anchor" point. You can try this hack - http://forum.coppermine-gallery.net/index.php?topic=35140.0 (http://forum.coppermine-gallery.net/index.php?topic=35140.0) or maybe even write the webmaster of the site you linked to and asked how he did it. It looks like they're using an iFrame to hold the gallery.
I agree, it was a problem of integration with Joomla; this night I found this solution:
- rename the file joomla.integ.php in the Joomla-Coppermine bridge by Mehdi
- call Coppermine Gallery by means of Joomla Wrapper.
