Img proposals

[smolak]

Loader

I guess this could be a neat addition to lazy load / async features. Disabled by default, when on, controlled by CSS. Perhaps some default CSS?

All attributes of native img

I guess this doesn't require more explanation.

Various formats

I am not quite sure about this, but I decided to add it eventually.

Downloadable

Well, we download images from time to time. Instead of right-clicking thing, why not allow users to hit a button.

Licence

I guess we should also think about the authors of those photos / images. I have found some information here and here, and there was a proposal for a copyright attribute. Perhaps copyright will be better, as it can contain CC info with who is the owner?
