Hi there.. i'm just a normal user and not affiliated with photopost... i look into the forum often.. but its the first time i read that post...
anyway for what you want.. if I understand correctly you just have to switch the safe-mode setting in maintenance in the acp..
but its not wise to do so.. if you can avoid it..
you should not upload any files in the "files" folder!!! the gallery does it automatically... when a user uploads..
For each user it creates a folder by userid..
Example: if you as admin upload a file test1.jpg through upload.php.. it will automatically go to folder files/1/test1.jpg
If I upload a file test1,jpg to your site and my userid is 512 the file should go in: files/5/1/2/test1.jpg
If you upload your images per ftp.. then you should NOT upload them into the files folder but into gallery/users/1
1 being your userid.. (you can set another folder in ACP)
then you go to the upload.php where there is for you (if you enabled it in ACP) a section for mass upload.. if you do that.. the files will be sent to the correct folder..
ONLY if you have to.. (safe mode is enabled on your server) you can send all files just to the files directory without subdirectories.. for that you must switch the safe mode setting in the gallery -> maintenance section of acp.
Then you have ALL files in the files subfolder.. but beware:
Some servers cannot handle more than a couple of thousand files in 1 directory!!!! Thats why you should use the subdirectory system if your server allows it.!!!! ( dont forget.. you have 3 files per picture if you count thumbnail and original - some servers will also get very slow the more files there are in 1 directory)
hope that helps
