While Alf has an 'Alf way of putting things

' he does have a point addressed by Alex - "take it on board".
A forum is by definition a disussion centre - so if you want comments on your photo's then load them into the gallery and possibly somebody may add a comment or not.
If you want to start a discussion on a photo (the way it looks, how could it be improved, is it good enough - whatever) then post it into the forum. (you may still not get any discussion though - depends on if anybody has anything to say about the photo....)
I don't mean to put anybody off the forum or web-site, it's just easier to follow the conventions sometimes.
