Saving image coordinates

[ihenman]

I have an I frame that allows users to upload their own pictures manipulate them etc. (resize, drag, drop, copy etc.)

Now I need to offer them some form of saving their work. I can easily store all the images and such theyare using in a Database via PHP, but how can I store the exact place where they have the pictures placed so that when they come back to it, and load their page the images are in the same place at the same size?

Can I some how store coordinates of the pictures? Or possibly % increase or decrease in size?

I'm using DHTML and Javascript to do the draggin and dropping as well as resizing? IDEAS..

thanks
