Sometimes if your galleries have long titles, the gallery thumbnail pages can get overwhelmed with too much redundant title text. The "Gallery Thumbnail Title" solves this problem by giving you the option to have shorter gallery titles names to display under the thumbnails.
For example, let's say you have a Canyonlands National Park gallery that has lots of sub-galleries with information about Canyonlands National Park. The gallery list might look like this:
- Hiking in Canyonlands National Park, Utah
- Viewpoints of Canyonlands National Park, Utah
- Camping in Canyonlands National Park, Utah
- Photo Tours in Canyonlands National Park, Utah
In this case, it makes sense to include "Canyonlands National Park, Utah" in all the gallery page titles, both for usability and SEO purposes. But, when you are looking at the main gallery page that shows all these sub-gallery thumbnail links, the page is overwhelmed with these long and redundant titles. By entering shorter "Gallery Thumbnail Titles" for these galleries, the main Canyonlands National Park gallery page could looks a lot cleaner, showing thumbnail titles like:
- Photo Tours
Thus, you can have the best of both worlds: Short and succinct gallery thumbnail titles and longer, keyword-rich gallery page titles.
