Ajax by its nature deals with textual information only, be it HTML, XML,

Exactly, thus an XMLHttpRequest can be used update an image in two ways:
* The image URL can be passed as information to the HTTP response,
wrapped in XML or not (i.e. XMLHttpRequest.responseText). That can be
used to update an image.
* The actual image data can be encoded in base64 and sent in an XML
envelope obtained by an XMLHttpRequest. The base64 string can then be
used with the data: URI scheme[1] to render the image.
