It's not mine! It has
its own page on the American Museum of Natural History site.
As far as the feathers not being feathers (per that AiG claim), that's pretty debatable.
A clue to what's going on: this is probably the second Sinornithosaurus ever found. Much or all of the literature AiG and some others quote refers to the first fossil, a less clear and pretty (but fully adult) specimen shown below. There's more room for claiming the feathers might be something else on the first one.
Above, the first one.
Above, the probable second one (if it isn't a related new species).
Feather detail, first find.

Yeah, I know it wasn't yours but I knew you had it bookmarked ;)
However, in the mean time I did a websearch and found the link on this
feathered dinosaur website.
Just wanted to post it but you beat me to it.
So thanks again for posting it and saving me some work ;)
As you said, whether they are indeed feathers is debatable even in evolutionary circles. And, as I said, feathered dinosaurs don't equal transitional species any more than hairy long tailed dogs equal cats.
