Hi Mary,
Thanks for this suggestion!
In case you aren’t aware of this, you can actually upload any image you’d like to use as a sticker to the Photo Basket (at the bottom of the editor). So, you can find any image you like on Google Image Search or anywhere else and then use it as a sticker on Ribbet.
Once uploaded to the Photo Basket you can drag it onto your image and resize it, just like a regular sticker.
Let us know if you have any other questions or suggestions!
