Do you mean that PIL doesn't read the DPI attribute from the file, or  
shows a different value than expected?

Using which file format?
DPI is just an indication, a reference value. Changing it won't modify the  
image size in pixels, quality or resolution. Maybe you could post some  
sample code showing what you attempt to do.
