How can I have my code access multiple images automatically?

I have multiple images in a folder, for example 'img1, img2, img3' How can I make my code access those files with specified names automatically? I've been using uigetfile and imread but both require manual input.

you can use the function dir() such as files = dir('*.jpg') which will return the file information for each jpeg into a structure. then a simple for-loop to access files.name (given my example of files) to loop through the jpegs in the folder.

air coding so pardon function call mistakes:

 folder  = uigetfolder();
 jpegfiles = dir(fullfile(folder,'*.jpg'));

 for imageNum = 1:length(jpegfiles)
    importedImage(imageNum).raw = imread(fullfile(folder,jpegfiles(imageNum).Name));
 end
