thanks for the replay! i have PIL and pillow-11.30.0 dist in the correct folder. keep getting the same error.i think for some reason, the add on is not getting the right path to the install site-packages.

Could you run this from the command prompt:
"<Path to Blender>\4.5\python\bin\python.exe" -m pip show Pillow
It should give you info about the library including the install location:

This is the output from mine. I just want to see if there is a conflict with the install location from the pip command side of things.
I feel like you are super close to getting it working!
