Wallpaper Tool

The wallpaper tool is ready! Originally didnt have plans to make one but you asked for it so here it is ^^. Thanks for the feedback on how the tool should behave.
The tool lives here and is linked to from the navbar in the header. When you visit the page, you will see the following...

Click on the image of your choice and then proceed to enter a width for your wallpaper. The tool detects your screen size and if you click on the "click here to make this size" link, the width and height fields will be automatically populated. When both width and height are designated, the top/bottom of the image is cropped. If you leave the width blank then the image keeps its aspect ratio to the width of your choice.

I didnt fancy making different wallpaper sizes so came up with the idea of this tool that allows you to help yourself - I wanted to cater for all including mac users with wide screen displays. The only people I cant cater for is for those who have monitor sizes of over 3000px wide (rich folks^^;)

As you can make wallpaper of any size, you can also make images for your iPod, mobile phone, PDA or whatever tickles your fancy.

I'm lousy at making wallpaper images and threw together some of the new mascot. If you have any requests, rummage through the Galleries and give me the photo ID (the image name) and a brief description of what the image is. Better still, post the path to the image. Will upload if I can find the original ^^;

Works fine on my local development server but not sure how memory allocation behaves on the live server with multiple accesses - let me know if you find a bug or have any other suggestions.
I will be constantly adding new images and removing unpopular ones.
Also, let me know if you would like the ability to upload your original images so that you dont have to make a zillion different sized wallpaper for your users.

Do what you want with the images but please observe the Creative Commons Deed.

Technical details: When I want to add new images to the wallpaper pool, I take the original image and upload it to a folder via FTP. Every time the tool is called, the script checks the wallpaper pool directory for new images. If there is a new image, it generates a thumbnail which you see in the pool.
When a user generates a wallpaper, that image is saved in a directory for others who want the same image in the same size. The wallpaper directory is flushed every once in a while.
GD library is used for image handling and the whole tool runs on PHP and some AJAX.
