Adding visual elements (such as pictures, maps, or charts) can really enhance your speech. Make sure to always pay attention to copyright restrictions and give credit to the source for all images you use.
Search Google for pictures, maps, or other visuals to supplement your speech.
Tip: You can also try a Google Images search. After you've performed a search, select "Tools." If you choose "Labeled for Reuse" in the Usage Rights drop-down box, you'll ensure the images you use are not violating copyright licenses.
