How can I have text explaining the image only show when in full view?

[Hummingbird]

Hi.  I am wanting to have text that goes with an image -- say, an Edgar Allen Poe poem -- only show up once someone has clicked on a thumbnail.  Now, all of the text shows under each thumbnail, and it's very sloppy-looking. Any ideas?

Thank you.

Login as admin and go to Config> Thumbnail view > Display file caption (in addition to title) below the thumbnail. Below this are the other items you can remove from the thumbnail. Read the manual too!
