Seems like I got this nice mod, originated by Fotofreek and completed by Stramm, working for CPG 1.4
I did use code from two threads but had to put it in different places with some very minor changes:

http://forum.coppermine-gallery.net/index.php/topic,32567.msg177637.html#msg177637 (http://forum.coppermine-gallery.net/index.php/topic,32567.msg177637.html#msg177637)
There is only one disadvantage, also in the version for CPG 1.3:
The changed code for next/prev in displayimage.php does not work correct with meta albums. Instead of going to the next/prev picture that was shown in the meta album you go to next/prev in the fixed album where the picture belongs to. Would it be possible to make this work better?
The mod in CPG 1.3 can be found here:http://www.victorbos.nl/ (http://www.victorbos.nl/)
My version for CPG 1.4 is working here:http://basdekker.eu/beeldbank/ (http://basdekker.eu/beeldbank/)
For who wants to try this mod:
I did use the mod part from trev98:

but put in on a better place, in yourtheme/theme.php
The other part for next/prev buttons is Stamms last codeversion from this message:

Put this in yourtheme/theme.php in the right codepiece.
