Using Google Image in Preview

Hi all, I am about to make a mockup template. Am I allowed to use a flyer of google images in the preview image/images as long as I dont include it in the final product/download?

Thanks

Anyone know?? plz

Only if they’re Creative Commons images that allow commercial use.

Unfortunately no . It’s very difficult to know under what license they are.
I recommend it :


And this, is just $5 image:
