I can see all the tags on a photo when only that single photo is displayed. If more than one photo is displayed, I only see a globe icon that shows that the photo is tagged. Is there a way to see multiple tags when more than one photo is displayed?
When any more than a single image is displayed, you only get the icon(s) for the categories of the tags you have applied. I cannot remember if SE lets you add more categories, but that could be helpful.
There are 2 ways to see the list of tags:
1) Point at the category icon on an image and it will display the list.
