Hi,
I'm using a fairly recent emacs (24.0.50.8), but when trying to load an image
with
(put-image (create-image "pic.jpg") 0) ;; some normal 1024x768 jpeg image
I only get a little square, and emacs consumes ca. 60% cpu, with X taking a
lot of the rest -- this continues for at least a minute or so. I checked with
oprofile, I get the following profile (see below). So what is this
assq_no_quit doing?
Best wishes,
Dirk.

Could you possibly do a m-x report-emacs-bug ?
It would be nice to see your configure options etc.
Also provide a link to your image.

This is interesting: I now found that it's fully reproducible with 'emacs -Q'
(from trunk) if the image does _not_exist_ -- I found that because the image
had a typo in it's name, and this is apparently what I saw yesterday.
Find below the stuff that report-emacs-bug gathered. The only non-standard
thing is this --with-imagemagick, which I tried recently; but I don't think
emacs is using that for loading images. Interestingly, this is what I see:
#("x" 0 1 (display (image :type jpeg :file "~/pic.jpg02353_sunriseclouds_1024x768.jpg")))Cannot find image file `~/pic.jpg02353_sunriseclouds_1024x768.jpg'
Cannot find image file `~/pic.jpg02353_sunriseclouds_1024x768.jpg' [1496 times]
Making completion list...
Cannot find image file `~/pic.jpg02353_sunriseclouds_1024x768.jpg' [1346 times]
Interestingly, look at the [1496 times]. We go into some loop?
Of course I now tried with an image that *does* exist,
http://interfacelift.com/wallpaper_beta/grab/02353_sunriseclouds_1024x768.jpg
but that gives me:
#("x" 0 1 (display (image :type jpeg :file "~/02353_sunriseclouds_1024x768.jpg")))Error reading JPEG image `(image :type jpeg :file ~/02353_sunriseclouds_1024x768.jpg)': JPEG parameter struct mismatch: library thinks size is 464, caller expects 468
