Finding example images in the distribution

Is there an easy way to find all the example images (such as pout.tif, greens.jpg) that come with MATLAB and any installed toolboxes? This would be useful for setting up one's own demonstrations and giving code examples to other users.
I can find many by a recursive search on the MATLAB directory tree, looking for likely filename extensions, but I wondered if someone had provided a simpler way (e.g. just a list in the documentation) that I've missed.

I think this is a very good question. I also struggle with that when discussion image processing examples.

They actually changed where they kept their images when they went to R2014b. So this used to work:
folder = fullfile(matlabroot, '\toolbox\images\imdemos');
but not any more. So I've been told from the Mathworks that this is the best way:
% Determine where demo folder is (works with all versions).
folder = fileparts(which('cameraman.tif'));

Thanks - this helps, but there are images not listed (e.g. spine.tif, tire.tif), some entries don't give file names (e.g. "LAN files") and the filename extensions aren't given.

Hi,
This might be late. For me it's C:\Program Files\MATLAB\R2007b\toolbox\images\imdemos.
I got there by pure accident. I remember modifying cameraman and when I tried something like
imageTest=imread('cameraman.tif')
I got this error
??? Error using ==> rtifc
C:\Program
Files\MATLAB\R2007b\toolbox\images\imdemos\cameraman.tif:
No space to read TIFF directory.
Anyway,HTH.
Regards, Florin
