I'm not exactly sure what you mean. These lines of code convert an image stored in a disk file into a variable in your MATLAB program.
grayImage = imread(fullFileName);
rgbImage = imread(fullFileName);
To display them, do this:
imshow(grayImage);
imshow(rgbImage);
Those lines of code take the image in the variable and make it an image on your computer screen.
If that's not what you mean, then explain further, after reading this.
You can find several examples of this in my tutorials in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
