Does "C-l" restore the images?  If it does, the problem is with
something in redisplay deciding that images don't need to be redrawn
when they should.

If "C-l" doesn't help, I suggest to run the appropriate speedbar's
function (the one which puts images on the display) under Edebug and
see if it DTRT.  If that doesn't help to understand what's wrong, you
might need to fire up GDB, put breakpoints in the primitives called by
that speedbar's function, and see what's going on there.
