Yes, it seems to be taken (or faked) with a zero-lux camera. Some trail cameras use flash, but the images are infinitely better. For example see here.
With this said, it's nearly impossible to have this picture taken. The creature had to see the camera and approach it in darkness. The IR camera does not radiate anything until it is ready to take the picture (the battery won't last otherwise.) Such a camera would use a PIR sensor, and it doesn't radiate - it detects body heat. So the camera is 100% invisible, modulo scent - and a camera left in the woods for days will lose that quick.
There are also anatomical issues with the body of the creature. Its arms are so thin they would be either broken after a few days in this world, or they are made of composites :-) The nature doesn't make such beings for a reason - they can't survive. Considering that other people noticed that there are other versions of this photo, it is probably a hoax.
On top of that, there is that old problem of Loch Ness monster: a single creature or a tiny population cannot survive. Hunters know all about that. It is virtually impossible to have an unknown animal hiding in a populated territory; it would have to have some numbers, and then some of them would be seen alive or, more likely, dead. A chupacabra, if there is only one, has to be immortal and infinitely elusive, preferrably with a cloak of invisibility that is powered up most of the time. Even an intelligent ET, with smarts and technology, would find it problematic to hide from the locals for long.
Yeah, the physiology is very weird. Huge shoulders and arms like toothpicks. With shoulder muscles that massive it would probably break its own arms trying to do something they couldn’t handle.
