In CRM 2011, images are stored in notes as MIME encoded text. As a result, images get converted to a displayable format for every read and no pre-cached thumbnails exist. In CRM 2013, images are being introduced as a first class data type. You can now add images as a field, capture/store images and improve query operations on images.
You can capture and maintain images for User Profile, Contacts and Leads, and Account logos.
