where can I find pictures to use in my class to talk on?

Hi everyone,
I need pictures and flash cards to use in my class, especially for speaking lessons. I know a book called “Composition through pictures” and I have a copy of it. But I use the book for writing classes and I need more materials.
I am looking for serial pictures or cartoons like the ones in that book.

I will be very grateful if anyone helps.

You might want to create a keyword list describing the images you are looking for and then google those words to see what comes up.[YSaerTTEW443543]
