Well, I think I know what your trying to do. I'm guessing that you want to make a object and then TEXTURE it with an image. The reason why your getting that error is because your trying to make a object out of a image. Images are 2d like a drawing on a piece of paper, and an object is 3d like a human or a gun in real life. A image only has one way that you can view it which is directly on top of it, on the other hand a object you can rotate and look at it from different angles.
If you want to TEXTURE a object with an image you can. A texture is just a image that is wrapped around an object.
The code below will simply load up your image, make a sphere object, and then texture the object with the image. However, make sure you replace the "FileName.bmp" part with the filename of your image that you want to use, but make sure it's in quotes.
Load Image "FileName.bmp",1
Make Object Sphere 1,50
Texture Object 1,1
I think that's what you want to do, but I'm not sure.
If you really want to see what that code above does then run the code below, but just remember to replace the "FileName.bmp" part with the filename of your image that you want to use, but make sure it's in quotes. And if you don't understand the code below, don't worry about it because you don't really need to yet, it's just so you can see what the code I posted above is doing.
The controls:
-Right\Left Keys - Side Step
-Down\Up Keys - Move backward and forward
-Mouse - Looks Around

rem Camera Movement
Do
Cam_YAng#=WrapValue(Cam_YAng#+(MouseMoveX()*.5))

Rotate Camera Cam_XAng#,Cam_YAng#,0
If DownKey()=1 Then Move Camera -1
If UpKey()=1 Then Move Camera 1

If RightKey()=1

I hope I've helped, but if you have any questions or thats not what you want to do then just say so
