As shown in the title, how would I be doing that?
If you had a variable referencing the /image, you can typecast the variable and change it:
mob/var/tmp/image/marker = new('test.dmi', src)  //  this will not work as it cannot be defined at compile-time.

marker.dir = SOUTH

/*
var/image/I = src.marker // A round about way which will waste further time than the above
I.dir = NORTH
*/

Alright, I see. Thank you.
