Upload and image manipulation class

So you want to upload your files, but also validate extensions, size. You can use PEAR's HTTP_Upload class for that.

And then if you want to only upload images, and create thumbnails, resize images or crop the uploaded images, you can use the above upload class and this great Thumbnailer Class

This two classes make a powerful tool for uploading ,validating, resizing, cropping, rotating images or pictures.
