linking to external sites in exhibits - Omeka 2

How do you add href links to images that take visitors to external sites? I'm building a standalone exhibit. The top logo and several other elements have to link to pages / sites outside the exhibit. Have the images embedded ... need the linking convention. Thanks, Lyn.

I'm assuming that you put the images in via the HTML editor? If so, you can just highlight the image and use the link icon in the editor to add the url

No. I'm working underneath ... not using the editor. Does the link icon add something?

Tested. Sorry. This is not a problem.
