Ah, ok. Shout out if you need help :)

I upload pics from my 'phone onto my computer photos file, then attach the photo I want, to the post I want, by clicking 'photo' (the camera). That brings up my photo album, and I just select the photo I want.

OH and, by the way: I asked the forum administrators how to change a first post and add pictures; they informed me that a first original post by a member, starting a new thread, has only a limited time permitted for editing. Personally, I think that the fact that anyone can return to a comment they've made, in a thread, even days later, and change it, that application seems a bit bizarre, frankly...

Second one is a Haworthia, exact species I'm not sure, maybe H. pumila?

Third one might be a Haageocereus or Cleistocactus. It should grow columnar, and will be easier to ID when larger.
