[opencms-dev] API-question for Previous-Next-Links

[Andreas Graeff]

Hello,
good point Pavel, looks like the photo album fits most of my needs ;-). 
Especially I don't have to worry about date formating if I simple put 
the shooting date  into the description ;-). My mistake :-), I started 
developing with OpenCms 6.0.4 (actual customer installation), changed to 
OpenCms 7.0.3 yesterday.
But the question for the api remains for me, maybe not for the curent 
photo galery but for further development, where I want to have different 
kind of access to the parameters of a contentloop. Any ideas?
Thank you and Regards
Andreas Graeff
