Use the Random Words with No English Translation tool (http://lab.cogdogblog.com/nowords/) to generate a word that could be better understood with a photo or image. Find a creative commons image or make your own, and include the word somehow in the image (using a desktop photo editor or web tool like Aviary or PicNIk). Then share it with someone and ask if it makes sense.
