Installing images to phone

Hi,

I want to install images to the phone via my app's .sis file.
However, there seems to be a difference between the phone's memory and the memory card in this case.

PathInfo::MemoryCardRootPath() and PathInfo::PhoneMemoryRootPath(), return a path which is different. The Memory Card is E:\ while the PhoneMemory is C:\Nokia.
Now I want my app to look for it's images under ...\Images\MyApp. However this will be different depending on the installation target.

If the user installs to the card, the app will look in
e:\Images\MyApp
If the user installs on the phone, the app will look in
c:\Nokia\Images\MyApp.

So How can I write the .sis file to perform the installation correctly??

Thanx
