PhotoPost Performance FAQ
3.how do i know which version of photopost is installed? (the stats page is not working - keep timing out).
You can try looking in the adm-misc file or your database but yeah the stats page shows the version
4.what version of php should i use? The main thing that sucks my CPU performance is php-cgi. i understand that if i could run php isapi instead its faster because its already in memory . am i correct?
You would need to have your host diagnose what is slowing up on your server and take the right measures but yes isapi is faster than cgi.
5. RTL - right to left languages, since i am a hebrew user, i would like to know which files must be changed to RTL direction (on the new version i am ordering).
well rtl is in your language file metatag which tells wording how to display we do not support hebrew though. If your trying to change the template aligns you would need to edit all your templates and change the aligns backwards from the way they are now meaning left would be right and right would be left
6. i am ordering the new verison of photopost - should there be a problem - can i roll back quickly? or is it not recommended.
You cant really roll back since we dont keep old files
7.do u have a service where i could ask your guys to optimize my gallery (for payment of course)?
We dont really do server optimizations. The photopost settings you can do yourself really.
