I have just installed Photopress for my weblog, so I am not familiar with the programe yet.
My first problem was to create a folder named Photos in WP-content, secund to place the Photopress folder and the photopress.php in the Plugin-folder.
And finally to change the file atributes for the folders to 777.
Now it seems to work, and I have started to upload some pictures.
I will return, when i get exatly your problem
Regards
Mikael
PS.
Perhaps you will find a solution to your problem use the “Search first” in upper right corner seaching for Photopress (in one word – not two)
