Thanks, that did the trick. One thing I'm still having trouble with is
getting transports other than raw to work with
image_transport::SubscriberFilter. If I pass
image_transport::TransportHints th(transport) to
image_transport::SubscriberFilter, where transport is "compressed" or
"theora", I never seem to get any data. rxgraph -t shows that my node
is connected to my image publisher on the right topic, but the callback
never gets called.<br>
<br>
Thanks,<br>

a related note, is there a way to use TimeSynchronizer with
image_transport rather than subscribing to the image directly?<br>

Use <a moz-do-not-send="true"
href="http://www.ros.org/doc/api/image_transport/html/classimage__transport_1_1SubscriberFilter.html">image_transport::SubscriberFilter</a>
as a drop-in replacement for message_filters::Subscriber. It uses an
image_transport subscriber under the hood.<br>
<br>
