@Fox and how to upload an undetermined number of photos (chosen by user) from a folder of 1000 images, one by one, on a single session?
Example, the first execution the user upload 4 images, the second time 9 images etc.
I tried to get base64data from image file but it didn't worked http://prntscr.com/s6966f most probably because it needs image id, how to get this image id ?
