Straight forward; the rendering code just expects an Image to pop out of the URL connection so this is pretty easy to do (and is preferable to writing stuff out to disk). I assume that there is something about your feature (an attribute) that says which graphic to display.
Option 2: GeoTools only solution - beginner: make a GeoTools function that generates an image - advanced: the SLD specification allows for marks representing graphics that are "well known" to the renderer. They uses some examples like circle, square and so on but... you could teach the GeoTools renderer about your graphics. This is the approach taken for MIL2525B symbols in GeoTools; the work was experimental at the time and released to the public. Myself (or several other consultants) could make this happen for you in short order. Option 1 should make sense to you, Option 2 would involve reading the developers guide a bit (on how to add a new plugin) and diving in to the geotools render.
