I don't think any of them blink, though they are all animated; I have a high standard for animation though, in that they all have to be clean. (No flickering back to start positions, etc.)

To my knowledge, the only restrictions on images is that they be age-appropriate, that they not be copywritten, and that signature images be non-animated and smaller than the size limitations stated. (80x240 pixels)

I personally like those smilies a lot; they come out of a personal archive of smileys that I generally prefer over most forum smileys. I agree, though, that lining them up side-by-side would be a little hard for anybody to handle. My apologies. I removed all but the most appropriate.
