Downloaded DAM 5.5 and trying to import some big images but haven't had any luck. Can't use ImportSet at all with these files - get a Seam error. Tried http importer but it throws a different error

ImageMagick failed on command: resizer java.lang.NumberFormatException: For input string: “Empty”

then the transaction times out and rolls back and nothing gets imported.

Is it even possible to configure to import images > 2GB, and have imagemagic do its stuff, and get the image into DAM?

Thanks in advance
