Is it possible to do a drag and drop image with php to upload pictures to database?
If you use a front end library (Javascript) to catch the event of dropping the object into the page, and then submitting it via an Ajax request - yes it is possible. The other (uglier) route is to have a Java applet that does it (still through ajax).
I wouldnt store the images in the database though. Store them in a filesystem with the path specifics stored in the DB.
