First of all, thanks for the theme, I think it looks great.
I'm having issues with the Greyscale.
1) I tried inverting the greyscale effect, but as other have already mentioned, it doesn't work properly. Now the color will only fade in when i remove the mouse again from the tumb, but when the page loads, I get only the greyscale images.
See : http://www.kriesi.at/support/topic/invert-hover-effect-in-portfolio
I there any way I can make it work properly so I can invert the hover effect?
2) There's already a few topics about this, but no solution seems to have been provided yet. The grey overlay is a different size than the coloured thumbnail underneath.
At first, I was using the cropped thumbnails and and I managed to get the grayscale working properly by playing around with the scale of the image, but since all my photos where tall, I needed tall thumbnails as well so I decided to deactivate the cropping in order to keep my proportion. Now I can't get the greyscale overlay to be the same size as the thumbnail.
I disabled the greyscale, but here's my URL in case you need it : http://doperthandope.com/perseption
