I recently watched a video on YouTube that used two images simultaneously for front and side views. The images don't disappear when the speaker moves around the 3d-viewport. It's a little difficult for me to explain it in words, please watch the video to look at the image orientation.
I would love to know how that kind of image reference would be possible, because when I load any images they're only visible in one view and disappear when I switch the view.
Please let me know if any more information is required.
