559043 Online image manipulation sharing script

I would like to make a script that will reside on my server and allow people to manipulate images using a liquify like tool. This site has exactly what I want it to be... [login to view URL] I will also need a few modification such as a way for them to save the file they modify and share it on facebook and twitter. But i dont want the tool to be soly used on my site. I want to be able to have an "embed this tool on your site" feature so people can drop a code on their page and do the same thing on their site. I will need the following features: 1. have the user be able to save the created image on their computer 2. all images will be watermarked with my website logo 3. all images uploaded will be resized to a max width of 800px height/width 3mb upload max 4. The "saved" image will have a finished image side by side with the original 5. The script will reside on my server 6. a powered by tag will be at the bottom of the embeded widget that they cannot remove 7. there will am embed code button that will say "add this tool to your site". 8. Users will be able to share their altered photo on facebook or twitter with an option to include the original side by side before and after. In regards to the facebook and twitter links this will create... I would like the links to go back to the site that sent it to facebbok if possible. I would like the caption to read: "Get your new look in seconds" and a description explaining what the tool does.. I will give that to you later.. this tool will primarily be used for face shots so if people want to reduce their nose or face they can see before they get surgery what they will look like. The design should use neutral colors such as gray white black maybe a blue or green but not intense I am always up for suggestions if you have more ideas on this that can make it better
