Image Captions are the visible text that visitors see underneath images when they are enlarged. Image ALT Tags are used “behind the scenes” and are added to the HTML of a site. Since search engines like Google can’t visually "see" an image, ALT Tags provide a text alternative to help search engines properly identify and index photos on your site for better search results. Here's how to add both Image Captions & ALT Tags to images on your site.
STEP 1
Hover over any photo in your image library and click the "View" icon.
STEP 2
Click "Edit Caption & ALT Tag" on the bottom right corner of the enlarged image.
STEP 3
Insert a Caption and ALT Tag in the space provided. Click "Save" when you are done.
