Please explain further - I am not sure if I understand... (in case I do: Do you mean photo-realistic pictures of faces, or cartoon-type caricatures, or somewhere in between? It seems to me that SVG is in fact a fairly small hammer for most graphics nuts, and it certainly supports transparency and sprites (objects whose position and other properties can be animated) in a fairly lightweight manner. GIF and PNG support transparency for photo-realism - as far as I am aware jpeg does not (but I am not a graphics expert). But if you embed a jpeg within SVG you can clip it, set its transparency, use a filter or mask effect, etc. If you can describe an example I will try to produce it in SVG (by using bare code editing instead of one of the nice tools that I never quite get around to installing - try doing THAT with the source of a GIF <grin/>. However I think editing code is a silly way to author in general, and appreciate that this is valuable because you can also do it with graphics tools that have a more appropriate user interface).
