How do I post pictures?!

So, I'm pretty sure this is going to be simple but I can't be the only one who has problems with posting pictures... How do I do it? And (slightly unnecessary, but could be very helpful!) can you upload pictures through a smart phone? Thanks!

On the left on the front page, you have your name, and lower go to POST section, an there go to IMAGE, and then follow the indications. Good luck !

well the only thing is. only subscribers can post pictures. i think you're a member. so if you're selling something, you would just put links to any photos.
