Hi @vdiluoffo,

I tried your code on my machine and the callback is called every time a message is received. Could you give more detail about your configuration? (version of the code, rmw_implementation used).
How are you publishing your images? 

Note: I tested it running `cam2image -b` in a terminal and your code sample in another one.

Cheers,
Mikael
