Hi guys, I'm a PHP noob.
I have a small uploading form, but I get an error when I try to upload something. I don't understand why it's not working, because I use the same code snippet for another upload script, and there it works just fine.
Can anyone help me find the error please? 🙂
This is the error msg:
Warning: imagejpeg() [function.imagejpeg]: Unable to open '/www/htdocs/gal/galleries/1/loeb_aus_p2.jpg' for writing in /www/htdocs/gal/admin/gal_postphotos.php on line 16
