It's very hard to see the fullsize of an image inserted in a page

Do the following:

• find an image that is really large, larger than your viewport
• insert this image in a wiki page, with size parameters, to make it somewhat smaller
  • make sure the default parameters for image sizing are left to the default values in xwiki.properties for image size parameters to be rendered in the URL
• save the page and view it

Expected result:

• from the view mode, I would like to be able to somehow be able to access the original size of that image, if I want to go and see some detail in it

Actual result:

• if I open the lightbox of the image I get the image larger, but it's still not in the original size, it's maximized to the max size of my viewport and there are no zoom options in the lightbox - see XWIKI-19474
• if I right click on the image to open it in a new tab, it's the URL of the image that gets displayed in the new tab, which contains size parameters in it, so I will still see the image in its shrinked size. I have no way, as a regular user, to remove the size parameters from the URL to get the full image.
  • This works only if I open the lightbox and then right click on the image and open in new tab - in this case the image will be full
• as a side note, the download button that shows on hover of the page in view mode will download the small image (with size parameters), it's only the download button displayed once the image is magnified in the lightbox that downloads the image full

It should be easier to get access to the full version of an image, there are many situations where full images cannot be included in the page but need to remain accessible on reading.
