- If you specify an indexed image, then imtile converts it to RGB using the colormap present in the file.
- If there is a data type mismatch between images, then imtile rescales all images to be double using the im2double function.

From the help for imtile():
out = imtile(filenames) returns a tiled image containing the images specified in filenames. filenames is an n-by-1 or 1-by-n string array, character vector, or cell array of character vectors. If the files are not in the current folder or in a folder on the MATLAB® path, specify the full path name. See the imread command for more information.
By default, imtile arranges the images so that they roughly form a square, but you can change that using optional parameters. The images can have different sizes and types.
out = imtile(I) returns a tiled image containing all the frames of the multiframe image array I. A multiframe image array can be a sequence of binary, grayscale, or truecolor images.
out = imtile(images) returns a tiled image containing the images specified in the cell array images. imtile displays empty cell array elements as a blank tile.
out = imtile(imds) returns a tiled image containing the images specified in the ImageDatastore object imds. For information about image datastores, see ImageDatastore.
out = imtile(X,map) treats all grayscale images in X as indexed images and applies the specified colormap map to all frames. X can be an array of grayscale images (m-by-n-by-1-by-k), a string array of file names, or a cell array of character vectors. If X represents file names, map overrides any internal colormap present in the image files.

You can use montage() to display multiple images, or you can use the XData and YData parameters in image() to put the images at different coordinates of the same axes
