Inserting a Location oriented image into SWMM- SWMM5

Now it is necessary to design a drainage system , we must have a guidance of the placement of a supporting map. so what we do in we insert a backdrop image into swmm with which we are able to generate the pipe placement . But the problem with this is that when we insert an image into swmm, the size and location of the image is not in correspondence with the geographic location .
for the moment i will show you how to insert an image into swmm . in the next lesson  , i will try my best to make an image location oriented with the help of ArcGIS. the only problem is that ArcGIS itself is a very expensive software.

STEPS:

1. Menu 
1. View-Backdrop-Load
   
2. Backdrop image selector window
3. select the backdrop image from the browse folder button
4. select the world file from the browse folder button
5. select "scale map to backdrop image"
   
6. the image is imported , scaled and in its proper geographic location
