This will probably be more than you really want to know about toilets,
but here goes......
As of this post there are 3 toilets at the space station, plus other options.
The first is the main ISS toilet in the Zvezda module, an ASU-8A Waste Management System:

The toilet on the International Space Station located in the Zvezda module uses a fan-driven suction system similar to the Space Shuttle WCS.
Liquid waste is collected in 20 liter containers. Solid waste is collected in individual micro-perforated bags which are stored in an aluminum
container. Full containers are transferred to Progress for disposal.

A second permanent toilet will be added when Node 3 goes up:
An additional Waste and Hygiene Compartment is scheduled be part of the Node 3 module to be launched in 2010. In 2007, NASA purchased a
Russian-made toilet similar to the one already aboard ISS rather than develop one internally.
And as posted above, the one on Zvezda is now repaired and fully functional.
Could you imagine trying to use it though ?
Apparently a tight seal between the user and the device is very important.
The Soyuz return capsule also has a toilet, but is only for very limited use.
Before a launch they go through a pre-launch bowel clearing to minimize it's use.
For urination (with the control panel switch set to #1) a replaceable funnel is used. The waste is sucked into a collection tank (there are ten in
the module), and the air circulates through a charcoal filter before being sent back into the cabin. According to this post at CollectSPACE.com,
“women use a sanitary-napkin-type pad which absorbs fluid”, which doesn’t sound too appealing! If the electric air pump fails, a device with a
rubber-bulb hand pump serves as a backup.
For defecation (switch set to #2), a disposable bag is put into a container, which has an air suction tube connected to the container (the airflow
goes through the bag and a charcoal filter). A carton cover needs to be removed from the bag before insertion; it contains some sanitizing chemicals
and toilet paper (the latter is also removed). The user positions the device against their posterior. After finishing, a string around the edge of the
bag snaps a rolled rubber cover into place, hermetically sealing the contents. After securely tying it with rubber ties (similar to the ones used to
tie up the lining of the Sokol spacesuit), the bag insert is removed and put into another rubberized bag. This is placed into yet another bag,
hermetically sealed and placed in a waste container with other rubbish (it will all burn up when the Orbital Module is discarded upon descent).

The third toilet at the ISS right now is the one aboard the Shuttle, called the WCS.
They dehydrate solid waste and dump liquid overboard, and it looks somewhat civilized.
As mechanical as it looks it still doesn't have a robotic arm that will wipe your bum.

I think the picture mike posted in the OP is just a ground based mock up, not something that has ever flown in space. And no, there was never any real
concern about abandoning ship over no place to poop, they would use a baggy before they decided to return home.
It's a crappy subject, but hey, "Everyone Poops"
Thank God they don't fly elephants......
And if all else fails, this training information may need a revision for space travel...

Potty on my friends,
Our bodies have evolved to eliminate waste at 1G, but without gravity you will still need to go powder your nose or drop a bomb while you read the
sports section.
Go forth into the unknown, void your bladder & evacuate that bowel however you can.
Edit: And where the hell is Dr Love when you need him
This is a perfectly good defecating thread and I look forward to his input.
