Codex:

Gets an img tag for an image attachment, scaling it down if requested.

The {@see 'get_image_tag_class'} filter allows for changing the class name for the image without having to use regular expressions on the HTML content. The parameters are: what WordPress will use for the class, the Attachment ID, image align value, and the size the image should be. The second filter, {@see 'get_image_tag'}, has the HTML content, which can then be further manipulated by a plugin to change all attribute values and even HTML content.
