need help and ideas

I currently use Tiff image to display documents. Users needs to be able to edit or mark the documents/images.

For example, the document is a students homework. The student does his or her homework and scans the document. The scan document gets scanned as a tiff image and the teacher can now grade it. The teacher needs to be able to make notes or grade the document by marking it. This is a great idea don't you think? A student being able to scan their homework for their teacher to grade? (I have the technology to do this if anybody is interested.)

I know tiff images has the capability of doing this but I would like something more light weight. For example, PDF can do something similar to this. Is there anything else?

    why do you like use Tiff image for your work, it's very weight with large file size. you can cover to any formats like pdf, png. They are popular formats and easy using.

      Interesting idea! My two cents is for you to be able to accept multiple file types, convert everything to some standard type on your server, e.g., PNG, and then allow the teacher to make the changes online (with their mouse+keyboard?). Downloads should probably be done as PDF's so as to ensure that everyone is able to view/print consistently.

    Thanks for the feedback. Tiff is current our "Standard Type" and we do accept all type of images. I know that tiff is not light weight at all and I would like to know if there are any lightweight images and opensource functionality that has the capability of editing an image on the browser.

    The ideal image would be png or jpeg, but as of right now I cannot find a plugin or program to actually enable editing the image on a browser.

      Maybe I'm confused here. I'm envisioning that you read the file to memory, the browser interaction would change the graphic in memory, and the write the memory to a file. I don't see where you are ever editing a specific file at all, just replacing it. Sorry if I missed something.
