Are you sure this is the right place for your data? The tag is often abused, and it is intended only for short "captions:

A string that describes the subject of the image.
> For example, a user may wish to attach a comment such as "1988 company
> picnic" to an image.

I often see large XML payloads, proprietary acquisition data, etc in the tag, and this is totally incorrect.
