Hi, Some people don’t know this but, pictures, photographs and drawings belong to someone by authors law.
The pictures that you find in google aren’t free to use, unless you use them for something like your computer or phone wallpaper or just print them in your printer to frame it. You are using other people’s work to promote your account without giving any credit or asking for permission.
It would be okay if you would edit stock images to create wallpapers and stuff like that. This is not your pinterest account, this is a website to promote YOUR OWN ARTWORK.
You are just continuing the misinformation that any art you find online can be used freely. It belongs to someone and the download butt doesn’t give you the power to take appropriation of it.
