Maybe this will more directly answer at least part of what you're asking:
This forum is geared toward discussion, not just showing off your images. There is a Critique forum for those who want comments on their images, but it's primarily when you have an image you're unsure about, or have specific questions about, and want suggestions for improving it. If you just want to post a bunch of photos somewhere and have people say, "Nice picture", you'll probably just get annoyed with us, and us with you; there are other, better, places on the web for that. (Those who have been around here awhile will remember a few times in the past when such misunderstandings have occured...) If you travel interesting places that those here might be interested in seeing photos from, there's a Location forum where they would be welcome. Please don't inundate us with too much, though - remember to share the resources!
There are the occasional requests from some participants with slow connections to keep the images relatively small (certainly not full-res) so they don't have to wait forever for them to load.
Whether there are formal rules somewhere, I don't know - standard practice here has more evolved over time.
There are several ways to attach images to posts using the various buttons. You can post a link to an image stored elsewhere using the "http://" button (probably the easiest), post an image directly using the "IMG" button (but try to avoid making it too big - see earlier comment), or post a thumbnail that, when clicked on, directs the browser to a larger image elsewhere (I haven't done it in awhile and forget how).
