This is an HD pack of river rocks. The download contains all images in high resolution and transparent background. Free to use, even commercially, but crediting and linking back to my profile would be appreciated. To download all 17 high-resolution images, click on the button on the top right corner of the screen.
I am working on a game developing-oriented asset pack that includes these and more rock images edited with a filter to make them look cartoony. If this interests you, check back from time to time and eventually i'll have a link posted. Alternatively, you can message me for the files!
You can also message me if you want any other variation of these files, including their source images, edited versions, etc.
