Because I don’t know at all how we do it …
To upload your own, you click on the Art Catalog, then “Backgrounds: Available for ALL Stories” and then click “Upload to YOUR Account” and then select a picture and upload it. There are websites when allow you to change the size of the picture so you are able to upload it.
I have posted links to backgrounds on this post:
If you go on their linktrees, you would click on backgrounds/overlays, and it would lead you to a google drive where you can select images and download them for use on Episode and give credit to the people who provided/edited these BGs. However, if you want to upload a picture, then @Jules_Episode explains it perfectly.
Thanks for yout time
Moved to Art Resources since it’s about backgrounds.
