Making an array out of set of images in a folder

I am working on a gait analysis project. I have a folder,named silhouettes, in D drive that contains sub-folders and each sub-folder contains the sample images taken for a different individual. I need to operate on the images associated with each of the individuals by making an array of the images. But I am unable to find out a suitable syntax to create an array of images Hope I could get some help from users here.

Why do you need an array of images? Why not just read in the image you need. Or use the FAQ to read them all into a cell array if, for some reason, you need all of the images in memory at the very same time. http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

There's something called as the "average gait energy image " whose each and every pixel will have a grey value which would be the average of all the grey values of that particular pixel over all the images. So was thinking about performing the addition by running a loop through an array .

I'd just read them in and put each one into the slice of a 3D array

thisImage = imread(......)
image3D(:,:,sliceNumber) = thisImage;
