I'm new and I thought I was doing good by reading the FAQ before posting.
I saw the Picture Size heading on this thread but still I thought that must just be for attachments.
I assumed sites like FLICKR & Photobucket bore the brunt of bandwith and you were more or less re-directed to their sites from the embedded links when you used them.
Also if you want people to post no more than 2 photos at a time then why not set the limit at 2 rather than 4 as it is now?
At any rate since posting photos seems to be the thing to do around here this sort of regulation should appear in the FAQ.
Maybe I read the wrong FAQ
