I want to do some kind of image editor, after I upload more images I want to make a list with all the thumbnails!

After, I want to be able to click on one thumb and rotate, duplicate, drag and drop (to change positions of the images), and delete the image. I want all the images to be in a php array. If an image is deleted I want to delete the row from array too. If a image is drag-and-dropped I want to change the position in the array too.

Ok, after the user uploads all the images and modifies some of them, how can I make a DONE button to save the positions of the images?

For this small project how do you suggest I save the images? (to make a table in mysql and store the names of the images in the database depending on the session id? depending on the IP?)

Any suggestions are welcome!
