This can be a very useful plugin, thanks!
I have one question before installing it and hopefully the developer can tell me.
I normally use (Easy)Fancybox to show images in a lightbox effect. For that to work I link the thumbnail (or whatever custom size of the image) to the original (large version).
Reading the introduction of the Imsanity plugin, the original won't exist anymore, so how is this handled?
If I would have to go back in all Posts/Pages to adjust that link, then it will still be a great plugin to use, but only for new projects...
Looking forward to your response.
