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.

// Set upload dir where images will be stored, 
// this can be ABSOLUTE or RELATIVE path, MUST have trailing forward slash.

// Lets check to see if we are uploading an image file else print error $msg
