This question already has an answer here:
I set a background image (below) but it's not displaying while editing, and yes I'm not in ortho mode. Any ideas? Also attached a screenshot.
Update: this above part is now answered in comments—you must be in one of the preset ortho views or the camera view, and not the general ortho view or the perspective view.
I'm also interested in making this show up in my Cycles render, but it's not showing up despite having checked the Transparent checkbox under the Film panel.
Threads I've already read include:
- How do I set a background image while I am editing?
- Background image is not displaying in rendered mode
- I can't see my background image in the 3D view
