Hi Jason,

>From what you're writing I assume you have OSGeo4W package installed.
First, check if you have jpeg12_osgeo.dll installed in OSGeo4W location.
Assuming it is on C: drive, the DLL probably is inin C:\OSGeo4W\bin

Now, try to add C:\OSGeo4W\bin to PATH environment variable, open
console and issue this command:

C:\> set PATH=C:\OSGeo4W\bin;%PATH%
C:\>python
>>>> import liblas

Does it work?
