Well, like all these kinds of questions, it depends.
First, the distance veteran the earth and mars varies tremendously.
The Rover and all of the relay satellites in orbit send data at a rate
that changes with this distance. Right now the light travel time is
approximately 13 minutes one way.
Second, there are MANY cameras on the river and many different
resolutions resulting in pictures of different sizes. Further the
compression algorithms results vary depending on the image content.
Third the pictures compete with all of the other science data that
wants to come down and the links don't operate 24 hours a day. The
relay satellites are in low Mars orbit and get a few minutes over the
lander. So there is a major scheduling activity that precedes each Sol
(Martian Day), complicated further by that being longer than an Earth
Day by 40 minutes or so.
I am assuming that by now you realize this all takes serious computer
code to schedule and there is no one right answer.

How long does it take from the time Curiosity takes a
pictures/processesit for transmission to reception by NASA?
Is the picture sent in segments and does NASA use a 'checksum'
typesystem to make sure of proper reception.
Today's pics were better than I took of my dogs yesterday, and they
werejust a few feet away from me lying in my lawn!
