I want to grab the mean RGB values from all image files (.gifs or .jpegs) in a folder on my desktop. Is there a way to do this cleanly, without necessarily having to import all of these images, but rather just point Max to the folder?

not really. the patch shows you how to access a folder of contents.

for the other part of your question, did you have a look at jit.histrogram?

Edit: If you don't know how to open the posted patch, have a look at the sticky "Common Max Arcana" at the top of the MaxMSP list!!

Imagemagick can do that, so powerful tool !

For instance, this will give you the rgb values of the 2 main colors of a picture:

"convert picture.jpg -colors 2 -format "%c" histogram:"

See terminal scripts to apply this treatment for your entire folder.

With shell object you can launch the treatment and recover datas (zl queue for instance) inside max.

MIB: my reaction was actually to the patch once I opened it in Max :) Although I might as well have been reading the above characters.

I'll take a look at jit.histogram, thanks.

Samuel's method looks a bit like overkill. If you just want the mean RGB values, you don't need a histogram. jit.3m alone is going to do the job. The biggest PITA is just converting the filenames to absolute paths.

Just be careful with the patch below, if you drop a folder with a lot of files in it, it might look like Max is freezing, but it should eventually output the means.

Read mean RGB values from 200+ images in a folder?
