Hi, I'd like to add to Jastin's suggestions. Indeed, those are great options for finding crayon stock photos. Additionally, if you're open to free resources, you can also try out Pixabay. They have a vast collection of high-quality images, including crayon-related ones, and most of them are available under the Creative Commons Zero (CC0) license, which means you can use them for commercial purposes without any attribution.

Another avenue to explore is Etsy. While it's primarily known for handmade and vintage items, there are many artists and photographers who sell digital downloads of their work, including crayon photos. This can be a fantastic way to support independent creators while getting unique images for your project.

In any case, remember to double-check the licensing and usage rights to ensure they align with your project's needs. Happy hunting, and I hope you find the perfect crayon stock photos for your design!
