Plottable Thumbnail Library: Generate thumbnail images with caching support.

This is a class that generates thumbnail images on the fly. It may be useful for creating image galleries.

The thumbnails can be generated as the current script output or have its file data returned as a string.

The class supports caching the generated thumbnail images in server side files.

It requires the PHP GD extension. For remote files, url_allow_fopen must be set to on. If it is not, CURL is needed to access remote files.

Features Description:
- Cache
--> Thumbnails generated are cache-d so that you can access them faster should the content of the image not change
- Thumbnail
--> Standard thumbnail generation
- Auto-fitting
--> Need to fit an image within 300 by 300? Lazy to calculate the dimensions so that the image is not distorted? The class will do it for you!
- Scaling
--> Specify a scale to resize an image to! You can enlarge and shrink the image to as many times as you want!
