Hi there !
first of all thank you for this plugin it really help me out since i'm not really good in code and everything...
My problem is that even if the gallery is ok, whenever I click on an images to make it bigger, the plugin uses a cropped version of the image which make it small and incomplete.
I don't know how to fix that, I've tried deactivating plugins to find out which one was responsible for this but everything's fine as soon as responsive gallery grid isn't activated.
Have a nice day, Thank you !
