As part of a PHP based application which I have to develop, I have been asked to incorporate a feature which allows non-tech-savvy users to make a simple advertising poster, just some text & maybe images, possibly by choosing from a few templates, possibly by drag/drop almost like a drawing program.
I have argued that the user should use an external web page design program and then import it into my app, but to no avail.
using templates could be simple enough, drag/drop like a drawing program would require more effort on my part.
Is there any existing gratis software that would let me incorporate simple poster design into my PHP application?
