How do I increase face sprite pixel count without increasing face box size?

[enderhunter545]

So, my aim is to have my own images in there. I've got a friend making face sprites for me but I want a higher resolution than the basic 144x144 pixel set. I've figured out how to change this but the faces disappear entirely when I change it.

My main problem here is this: I want to keep the image to the left of the text at that size. At the same time, I want to be able to use higher-quality images than 144x144. How do I do this? Thanks

This image displays how it is normally at 144x144.


This (below) image displays how it is at 288x288. Not at all understanding why this happens.

you can't - the pixel number IS the resolution (or base therefor).

what you can do is use a show picture instead of a faceset for a larger picture
or you can use a plugin to change the handling of face pictures

but nothing will change the fact that for more pixels, the box has to be increased in size.
