Cheryl, to specifically answer your question ask why it matters ?

It matters if people post pictures
It matters if people contribute other ways too
It matters if people weren't posting pictures for the wrong reasons (there are at least a couple of members who will now start posting pictures)

As I said in post #144 up to each individual to determine why they do of don't, there's plenty of reasons for both

But I'll maintain that as a general observation that people who post pics learn quicker and that the forum overall benefits.
