Strange error messages, what I can do?

When I click to upload images, I get these error messages, and later I'm unable to upload any pic:


Warning: is_dir(): Stat failed for ./albums/edit/. (errno=13 - Permission denied) in /home/naif/public_html/galeria/upload.php on line 432

Oh, and I have read that I should chmod the edit folder to 777, or 755, but what is that exactly? I've tried to change something in the properties folder, called "Numeric Value", but it just doesn't let me change that!

I solved it, I just deleted the edit folder, created it again and then used such Numeric Value. It's just strange that I couldn't change the format before.
