The message is logged by image_error that has this commentary:
/* Log error message with format string FORMAT and argument ARG.
Signaling an error, e.g. when an image cannot be loaded, is not a
good idea because this would interrupt redisplay, and the error
message display would lead to another redisplay. This function
therefore simply displays a message. */
(That last "displays" should be "logs".)
