concerning open_basedir and safe_mode on fileupload

I am making an imagegallery with fileuploads for the members of the site and need a little info on how the open_basedir affects the fileupload. I have read what I have found on it, but I'm not sure what it really does. The phpinfo file says something like this: PHP CORE config. ------------------------------------------ open_basedir (local value) /dir1/dir2/yoursite:/dir1/dir2/tempdir (master value) No value safe_mode (local value) On (master value) Off ----------------------------------------- If I understood this correctly this means that I have to upload the imagefile to $sysfolder="/dir1/dir2/tempdir" Or would the $sysfolder be the whole value of the (local value): /dir1/dir2/yoursite:/dir1/dir2/tempdir And do I then have to move the file to the wanted directory for the uploads with a php script? And chmod(). Is this anything to have in mind? Final question: Wich of the values am I gonna work out from? My guess is offcourse the (local value), or I wouldn't get the: *Warning: *copy(): open_basedir restriction in effect. But I would believe the (master value) WAS the master value...if you get what I mean? Most of the time a "mastersomething" usually overrides a "notmastersomething".... Agree? Additional info: The upload is from a form and works perfectly on my own testing server where both safe_mode and open_basedir is turned of. Can anyone explain this to me in a nice "master to noob" way? Or is more information needed?
