Added to Wiki: image resizing and squaring library

[eluser]JoostV[/eluser]
Hi Glynn,

The lib is currently available on Github.
https://github.com/accent-interactive/ci-lib-images. I added a controller with some example code.

I advise you to use this version.

I the squareThumb() method will not resize, try to feed it the absolute path. (use only forward slashes, as the CI image library does not play well with backward slashes, see this thread).

See if this fixes your problem.
