I could not find any error, but the value of image-cache-eviction-delay is by 
default 1800 (30 minutes).  You can try to lower it to a minute or so and see 
if it helps.  Also note that Emacs only clears images after every 50:th 
redisplay.  A redisplay is done very often (C-x C-f C-g triggers one, so does 
displaying a tool tip) so that should not be a problem.
