Image annotation

How does the administration look to humanize the image annotation process a little bit?

Problem: If I need to somehow annotate the downloaded image, then you can use the alt tag, but the problem is that such annotation is not obvious. Those. the user will not see the text comment to the picture until he hover.
Example:
baryba rybaryby rybaryby rybaryby rybaryba
fish fishery fishery fishery

Suggestion: Make annotation more friendly, for example, as done at wired.com ( http://www.wired.com/epicenter/2010/01/ipad-mini-sim/ )
