/*
Oziams' Image Uploader example with basic error checking, you can use to upload
images as is or optionally re-size images and/or create thumbnails if required.
Image filename will be as original in lowercase, thumbnails will have the same
name as original with prefix "th_". Supports GIF,JPG or PNG images only.
This is just a basic example of how it could be used, of course you could
add more security checks and also display the image or thumb after upload if desired.
