When browsing between images, the left margin is not being update on the container, so the image / modal does not display correctly
Could it be a version issue? I just copied the latest Bootstrap Gallery files right in... I would think it is your Bootstrap version that is in conflict? Please check.
I just dropped the latest 2.1.1 in and no difference...
The width / left margin is not being changed, so wide images disappear under the right side of the modal
css: Bootstrap Image Gallery CSS 2.5
I guess that could be the problem!?
But just been looking at the files in https://github.com/blueimp/Bootstrap-Image-Gallery/
And they match with a 2.5 version for css and 2.8 for js. Does it work if you try to use the assets directly, without using the gem?
