"Leeman's July 9, 2014, Edublogger post pointed to a number of valuable sources of free images. Yet I'm wondering whether this resource wouldn't survive and possibly even grow if it were to provide seed content for a broad collective endeavour. Some parallels that spring to mind are Levine's 50+ web ways to tell a story wiki (http://50ways.wikispaces.com/50Contribute), and Tom Barrett's interesting ways crowd-sourcing endeavours with Google (http://edte.ch/blog/?page_id=424)." Another example is the iPhone Apps for the World Languages Teacher collection started by Isabelle Jones.
Teitelman's three top picks for free, easy-to use, online tools for editing images were: 1. Picadillo, 2. Pixlr, and 3. Fotor. Comments also mentioned a fourth, PicMonkey< three or four time in a fortnight.
The main objective of the World of Images collection is to provide copyright-free photographs for use in the development of quality educational material.
