* This script makes a photo gallery out of the images in its current directory. It is designed for pictures
* which were pulled directly off of some sort of digital camera, as it samples the pictures into both thumbnail size,
* and 'smaller' versions (~50k in size) which enables quicker downloading for simple browsing of the pictures.
*
* The full version of each picture is available from the script by simply clicking on the picture's respective 'full' link.
*
* Usage instructions: put this as the index to the directory which contains all the pictures.
* Load the page to generate the thumbnail and 'small' version cache. If you experience problems with a particular picture,
* simply delete that pictures thumbnail and small version in ./thumbs to have it regenerated. Deleting ./thumbs will cause
* all of the pictures to be regenerated on the next page load.
*
* Some web hosts may restrict the number of seconds a PHP script can run. If you have a large gallery (or more likely large
* pictures) it may take several page loads for the gallery to load successfuly. However, once the images are cached, there
* should be no problems loading the gallery quickly.
*
* Also, if you have multiple galleries, I recommend puting the script in your home directory and soft linking to it. This way,
* if you have the need to change the script, you don't have to change every version ;-). Dynamic titles of galleries is supported.
* Simply put a file called "title" in the same directory as the photos, and put the title of the gallery on the first line of that file.
