Issue when switching page to add images to a gallery

"Human readable error message:

Required request parameter 'imageType' for method parameter type int is not present

Root cause:

Required request parameter 'imageType' for method parameter type int is not present"

This is what I get when I try to go to the next page in "available images" to add to a gallery. I can only see the pictures on page 1, but as soon as I click on any other page, I get this error message. Why?

Hi there,

Cheers for the report.
I'm going to take a peek at it as soon as possible!

Fixed !
(easier than expected)
