Here's test builds from the trunk r6265 for ixus190 firmware 100d and 110a. If anyone knows the status of what has been tested in this port, or thinks it is/isn't ready for the autobuild please let me know.
Also, if someone who has the camera can post a sample jpeg (unmodified, not on a site like imgur that messes with the exif, you can take a small jpeg and attach it here in zip) that would be helpful.
