I want to implement "elements tagging" (Based on their positioning)on any given image file.
However I do not to want wish to use HTML5, since offline viewing is required and I don't the solution to be dependent on users' browsers
In Fact I wish to generate a new "file type" and a viewer cable of reading those files.
Also I want it to be difficult to extract the original image from the new file.
Which technology would you recommend for this kind of project ?
