a loss feature of 2.79...

its not the camera is the image plane, i know use of camera, this feature of background image i use for modeling specially, in a hour i edit the post and upload images of example, in 2.79 look in the viewport not in the camera

Look both links

i think i know what u are saying i post this in the comment of before, i looked this feature, its a image background but in the camera, for that u need cameras and change cameras positions, angles, isn´t the same, its more cumbersome and lose of time, so many thinks as changed of site and losed amazing features for that

in 2.79 is of that form: (its a model i made to print)

look this: youtu.be/0lF4hYKEI-U

(usually i work faster pressing shortcouts for the changes of view, in the numpad, but it wasnt my pc and dont have numpad, too i dont use the options for select a view for that i need hidden 1 image and unhidden another boths are in "all views")

You still haven't looked at the second link, haven't you?

yes but sorry i looked badly, but continue dont being the same it´s like maya or 3d max

but... every time that feature is going to use in top-right-another predefined views, u spend more time putting the posittions of the plane, could add 2 buttons, 1 for put it on specific view, and another for hidden in other views?

now:

• select a empty
• put like "image"
• select properties
• select the image
• hit the plane and rotate
  • planes every time in middle of the view u need hidde them
• and it x2 or x3, each time u want put a 2/3 planes

feature:

• select empty
• put like "image"
• put the settings (Add image, view and hidde on another views) with buttons
  • add button with list: views
  • add checker: hidde another views
  • add button more planes (it create another one in the settings and can be configured like the another, all in one panel)

i upload a image on bottom of the post

u could win seconds every time, thats not much on a single use but with a week and more reduction of times in another ones it reduce a lot of and that improves workflow

its me last post on this one, sorry for the inconveniences

just drag and drop from the file explorer to the viewport in whatever angle you need, and change settings of all empties at once using alt.
