I'm really admired by CiviCRM and very thankfull to all developers. Firstly it seems a bit complex and there are some tricks to learn, but I found all answers in the support documentation and forum. It makes me believe we're living in 21st century =)

I really like the pligin, but found a minor misfunction: if I change an image size with several iterations (i.e. more than one mouse click) it gets thumbnail dimensions of the first iteration only. I think it's better to get final dimensions that are when I save the article.
