Image path corrupted by +1

[edequal]

The images are not visible, and the pathway seems to get corrupted on the way from draftfile.php to pluginfile.php

E.G; the image is visible on editing mode to the teacher, but when the students starts an attempt, the student doesnt see the image, but if i change the pathway i.e change the folder name. (Have -1 the original folder number) The image appears.
