Hello,
I am complete newbie to Blender even to 3dprograms at all.
I have a question i had set a backgroundimage.But all of a sudden it was gone.I tried again to set it back again. But it won’'t appear.I can only see it when I am in camera view.Maybe someone has have this before.
P.S. Sorry for my English I know it’s really Bad.
Thanks in advance
Make sure you’re in Top, Front or Side view (7, 1 or 3 on the numpad) and that you’re not in Perspective mode (5 on the numpad).

Okeeh My problem is solved.I can go on with my work.
You can make stupid questions as a newbie 
Thanks
No question is “stupid,” except the one you didn’t ask. Because: (a) everyone is a newbie on some topic, and (b) someone else out there is banging his head against the very same thing … either right now or in the future … and will be very grateful for your post.
When I read your problem, these are some possibilities that I came up with: - The “normal” vector on the background plane is facing the wrong way. Try “Flip Normals.” (The “normal vector,” basically, describes “which side of this thing is ‘the front side?’”) - The “clip range” of your camera does not extend far enough away from the camera to completely encompass the background object. - The material setting on the object is incorrect or missing. - Nothing is illuminating the object.
HTH someone… (Who? Why, you of course! Hello there, whoever and whenever you are! How’s the weather? Mum and Dad are doing fine, yes? …
