You will need to install the most recent Haiku nightly image:

http://www.haiku-files.org/

Get one of the gcc2 hybrid images for this testing.  You need to check each of the tickets that show in the trac query linked below to see if they are still valid.  There has been a lot of work done on ShowImage in the past few weeks so some of these tickets may have been fixed in the process, and some may not even apply anymore.  Check each one carefully and report back here with your findings.
