Thanks. I did forget to activate gd. Fixed that already.
However I still can't get into the admin.php. Even when i manually type the url I get nothing. It really confuses me.
I reinstalled zenphoto and it's database. Setup works fine. I then have a choice to view the gallery (which works fine) and going to the admin section. When I click the latter (I checked the url) I get a blank screen. I am about to cry
On a sidenote. Not all thumbs seem to load all the time. I read in this forum people change the cache memory from 8 to 150mb, by adding two lines in the .htacces file. Maybe this is another dumb question but where can I change cache memory, I am not using the .htaccess file. Or could it be that the local server I am using is too slow to handle all this php and mySQL stuff. Please have patience with me I only started learning about setting up my own server
