Admiror gallery problem php 7

[ledkam]

Hi, i´m problem with image manager this photo component. If i set up webhosting php 7 (i have Joomla 3.6.5., Admiror gallery 5.1) i don´t open image manager in administrator correct (without error, see image - https://ulozto.cz/!I9UoDyAey77w/admiror-php7-png). If i set up PHP 5.6 i open image manager in Admiror gallery without problem.

Any idea please?

Thank you very much for answer.

If i'm right the "admiror Gallery" version 4 is not intended for Joomla 3 so that might be the problem.
