Choose a Display Mode for how thumbnails will be shown in your collections.
The display mode is set from the collection display options:
For all Corporate Clients and Stock Library, now we only show the "Keywords" and "Caption" fields if they are non-blank (otherwise we completely hide those labels & table rows). However on Stock Library we always have a caption because it doubles as a link to the 420px image for SEO.
On the Standard display mode, if an Events and Galleries file has a caption, we print it below the buttons & above the download links. We make the first word act as a heading to give a boost to that text for SEO without altering the way it appears.
