Try to string your images together into larger images. For example, instead of imagining Cat, Bagel, and Telephone as separate images you would imagine a cat in the middle of a bagel on the phone. Also connecting it to real life is very important, so you could make it your friends cat inside your favorite kind of bagel talking on whatever kind of phone you have, and that way it'll be easier to remember. If that still doesn't work for you, you can always place the images in locations that you are very familiar with.
