You say put them in parallel, they say don't put them in parallel. LOL... This electrical shit is confusing.
What "they" meant was probably - don't put LEDs in parallel with a single dropping resistor. Each LED has a slightly different forward voltage so they'll end up "fighting."

You can put strings of LEDs in parallel if they each have their own dropping resistor.

Here's a quick diagram to demonstrate what I'm trying to say...



BTW, the resistor value has to be varied depending on the number of LEDs you have in the chain. Is your supply source 9V or 12V? Is it possible to mount the batteries on the camera somewhere and have a curly cord going to it?
