I have recently set up a Wiki for others to use. I have no issues adding images myself. The users are not interested on the underlying (brilliant) Dokuwiki engine or even the concept of it. Having read others pages, for them it is just a tool to enter their own page of biographic information and some photos bring it alive. So they will be at the bottom of the learning curve.
Question:- What is the best aka simplest resource or mode to facilitate New Users adding photos when they are just looking for a simple functional solution? They may be Mac users who seem to have a low threshold for frustration with user interfaces too.
