You give the link url photo with your URL Link.
example: if you after upload photo in wordpress blog, so you can bold the photo and give the link.
My advice, use seo image plugin, so you can give description in the photo.
You can check the example photo in link source

use this code

<a href="URL1"><img src="URL2"></a>

URL1 is your twitter or myspace web address
URL2 is the direct image URL
