Hello/Hi/Greetings,
When I click on an image it says that the selected image size is "original", however, it's not. If I click on "original" again it resize the image correctly. When I click on another image it shows "original" again, even though it is not.

I am having similar issues. My findings to date suggest that Piwigo may be responsive, in that it responds to differing screen sizes, but it does not adapt to HD / Retina displays. I found a helpful site at https://www.kirupa.com/html5/detecting_ … gh_dpi.htm . This explains the concept and has a demo script to show what sort of display you are working with.
On my desktop (a fully patched iMac running the Safari browser) when I am on the photo page, the form title and the text when hovering the mouse displays the original file name. I have to right click and start the 'Save image as...' dialog to see the file name of the image being displayed.
Good luck with your investigations!
