I usually insert the image using the lower-left coordinates as the insertion point and asign to the image it's size in x (in meters).

To do this I use coordinates in projection (so they are in meters) and with this it works.

Hope this helps.

You can create georeference text file. It should have same name, and I think PCW extension or TFW (it's for tiff images).
In this file there are 6 lines
1. scale x
2. rotation 0
3.??? 0
4. scale y (with "-" direction )
5. x left corner insertion
6 y upper corner insertion
There are few corrections parameter but I don't remember
