It's done and it was actually not much work. And this will be the last release of the 0.3 branch. I will fix bugs for 0.3 until I released 0.4.

Here are the things that are fixed/changed/added:

• Replaced str_replace() with preg_quote() for regex escaping.
• Added separate sorting options for images and directories.
• Made private methods/variables protected to make extending easier.
• Added filesize limit option.
• Added (preview) thumbnail generation for directories.
• Changed markup for thumbnails. It'll be easier to style it with CSS.
• Added memory peak usage to the example page (index.php). Now you can see how much memory GD (not ImgBrowz0r) uses.

Not that much, but there's not much to add anyway. ;)
