You can add tags to your gallery. The tags will appear on the thumbnail of the gallery when you are on the Photo Gallery page of your website.
Open the gallery you want to edit. You do this in the same way as you do to edit a page.
Do one of these:
Click on Galleries in the back office and find the gallery you want to edit.
Click on the gallery itself on the Photo Gallery page in the front-end and then click on Edit Gallery at the top of the page.
You will see Gallery Tag Options in the sidebar on the right-hand side.
Simply check (tick) the tag(s) you want to use.
Click Update.
You can create new tags. Hover inside the box where the tags are listed and a + sign will appear.
Click it to add tags of your own.
Click Update.
