2. The display details function for an individual media item under the Album tab display, does not show the Type – this can only be seen by moving to Edit mode
I have now added a new paragraph to the Album FAQ page. to help with that. It says (with pictures):
Review existing “TYPE” tags
There are a few ways you can review your existing “TYPE” tags. Individually you can check and edit an object’s TYPE tag by selecting “View details” for any image, or by clicking the file name / title displayed [not the image itself] wherever it is displayed. To review the TYPE settings in bulk go to Administration > Media > Manage media. The TYPE tags for every image are displayed in the right-hand column there.
