Hello there,
I want to mention some bugs I noticed on this really great module.
1st: "Use K2 images" doesn't work. If someone doesn't want to create thumbs (preventing server overload) and prefers to use K2 images (you should add a box to choose size XS S M L XL) gets an output without images.
2nd: "Author name". When you choose ALIAS you get the username of user. Not the ALIAS.
3rd: Not exactly a bug. When you choose auto animation (pagination enabled) you should add on js to pause the interval when mouse is over the module, so when a visitor reads a page, the auto animation will turn the page after interval ends. Pretty annoying don't you think?
