Ah, well you can find them and similar images on the websites I have listed here: Copyright free images resource under " “FREE USE PNG SITES FOR OVERLAYS”. The ones I use most frequently are pngegg.com and hiclipart.com < they tend to have pretty high quality downloads. and tinypng.com for any overlays that are too big for episode’s 1Mb limit. It compresses without taking quality.
