Robert, 

Only some of the formats support creation of output files. The high level
formats list, and the individual format descriptions should (in theory) address
what is possible.

What version of GDAL are you using? The last source release predates the
addition of Erdas Imagine write support, even though the online documentation
(and code in CVS) supports this. 

You should be able to translate to formats such as JPEG, MFF, PCI .aux, and
PNG (with various limitations) using the release version of GDAL. If you
are intersted in Erdas Imagine .img support, I would suggest building GDAL
from CVS. 

Best regards,
