Seems like you'd already be aware if you're in Hong Kong, but Wechat will send images in original quality with zero extra screens and one extra click, and the images appear in the chat.
It also helpfully censors any messages that the Chinese government deems inappropriate. Perhaps not a good suggestion, especially as alternatives have already been suggested.
I can only go by personal experience but it seems that there are two WeChats; a mainland China and an international one. They can communicate with each other but the mainland version blocks content that violates Chinese laws.
My friends from the mainland (but who live in HK) were sending me plenty of photos of the protests and none of them seemed to be blocked.
Yeah, reading the articles back, it seems I've misremembered. Sorry, I'll edit that part out. Also, sorry for piquing your interest and leaving you out to dry, should have re-read the articles for proof beforehand.
