Not too sure, but I think this might be in you php.ini file. I would look in that file to make sure that the path is specified correctly. Do a search for "pear", because php.ini is a fairly long file to scan by eye.And I also notice in that error it says, "(include_path='.;C:\php5\pear')"
I don't have that folder structure. I have this:
C:\wamp\bin\php\php5.2.5\PEAR
This may not solve the image handler problem, but it is obviously an error worth looking into.
The image handler problem may be solved by re-uploading every file making sure the file structer is matching exactly. I had something like the same error and found that it was because I misplaced one of the many files during the upload process.
