Free word search maker
from Tools for Educators lets you make a word search puzzle with text hints or image hints. You must type in the text that you want entered into the puzzle. Just selecting the image will not enter information into the puzzle. (See below for an explanation of why that is.)
You can toggle between text and image hints if you are using the images groupings, but for more options with text only formats it's best to use the text only version.
Hint Type: NATIONALITIES -- IMAGE
