Is it possible to use captions in html image gallery?

Q: I’ve been searching for a gallery with thumbnail plug in, and yours seems perfect, except for one thing. Is there a way to use the caption from the image metadata?
If so I would like to order right away.

A: Actually, you can add any comment or text about the image. Select image by clicking and type your text in the field.
File name of your image appears in this field automatically.
