Zooming in on background images??

Okay, I am attempting to build a bakery using a background image blueprint, but when ever I zoom in to get a better look at where I am placing my planes…the background images loses it’s scale of things and goes wacky…so then my planes are totally off from where they are supposed to be. Anyone have the answer to this problem??

I am a noob myself, but I think that meshes and objects are diffrent to background image and so when u zoom in on an object, the background image stays the same. But you can manually scale the background image you know or have 2 windows: on with normal and another with a close-up zoom to get a better view. Hope that helped a bit. good luck;)
