I also tried resizing my chosen pic to 500 pixels wide, but it still OVERfills the space in the exact same way as when it was 850 pixels wide, only now it's at a lower resolution. Reducing the pixel size of the original doesn't seem to help. What am I dong wrong? My pic's aspect ratio is about those of a bumper sticker (500 x 130).
Also, is the "cover photo" the only one I really have to worry about, in terms of not having any sales or website references on it? All other photos, I can leave as is, yes? (most of them say -- on them -- "Like us on facebook" + have the main website address on them -- and say "SHARE this!!"
PS: A webinar I saw recently kinda used scare tactics about how people are gonna be banned if their new timeline formatted page(s) have calls to action, etc. in the wrong places, etc.
