EZ thumbnails

[paulm]

New version. Probably/hopefully it's final (ftb, except for bug fixes) since it does everything I need myself for now

1. Removed some debugging lines which I forgot to remove the previous version (some unused POST en SESSION vars).

2. Added "Safe Mode" usage option, which is true by default. In "Safe Mode" subdirectories (like images/dvd/ for an image like images/dvd/a_bugs_life.gif) are not created automaticly, you need to create those yourself. Not really EZ... I know (the option to do this automaticly is still available though). If you never put your images in subdirs of the images/ dir, or after the subdirs are created, it will make no difference.

3. Added a small readme.txt file which hopefully explains how it works.

4. Modified the code so that no error message will show if subdirectories do not exist and can not be created. That way you can chmod the thumbnails dir at any time to make it unwritable, without the risk of error messages to be shown.

5. Upgraded version number to 1.0
