Rhiannon -
I think the rule at present, if I read it right, is that if you own the copyright to the pictures, you can post as many as you want, but if you don't own the copyright to the pictures, the limit is one picture per person per thread per day (hence, the 1-1-1-1 rule). I think that even if you own the copyright, the mods would like one to limit direct downloads to the Forum to five pictures per person per thread per day, I suspect to keep the system from overloading under the weight of the images. However, I recall that if you link to an image which resides on a server of your own (such as your own web site), then you can post as many images as you like (since it's not overloading the BEA system that way).
Multiple reasons for the rule, I suppose, chief being concerns over gross copyright violations, with some worry over server overload (I recall a few times the system overloaded, a few years back)...
So, to sum up:
Pics you don't own: one per person per thread per day.
Pics you own, but upload to the BEA system: five per person per thread per day.
Pics you own, and link to from outside the BEA (such as your own server): go nuts.
Mods may feel free to correct anything I got wrong, and I undoubtedly got something wrong.
And welcome back, Rhiannon!
edited to add:I see others have answered the question; I'm a slow typist, sorry. But there shouldn't be a problem with the two Minka shots because 1) they're in different legitimate threads; 2) you own the copyright to them, so there's no legal problem.
All those shots are elegant and stunning, by the way, of yourself as well as Minka...
