external database of images to access within a matlab program

hi, im making a program that compares similairty between images. I want to be able to compare the input image with a database of images i can acess. the database doesn't need to be very long. It can be just 5 images. I just want some pointers as to how this can be done and what I should look at. Thanks

ps. all the images are jpeg

sorry i think i might have worded it wrong. i have made the GUI and everything for the program; i just want to access a database of images from the program which i can then compare with the users input image (psnr,graycorops,imhist,ssim,corr2,difference etc.) basically i want to know how i can add an image database to program. thanks
