Currently UI Vision can only search for one image at once. But I think you can speed your code up by using visualSearch:
visualSearch | image1.png | i1
visualSearch | image2.png | i2
visualSearch | image3.png | i3
-
If_v2 | ${i1} > 0 || ${i2} > 0 || ${i3} > 0
… do something
||
means “or” in Javascript syntax. So the command checks if image1, 2 or 3 are found.
