You only get a choice between low quality preview (image mode) and zoomed in full file (raindrop mode). Neither are very useful.
Able to preview images in actual uploaded resolutions. Images are currently too small to view.
Thumbnails for large images - this one is very high compared to its width - are extremely blurry as well.
That would be very helpful - it allows user to scroll through high-res images with arrows. Now I have to click on "Raindrop" tab every time.
@Oleg Shilin: Agreed. I'm trying to use Raindrop to organize images sort of like Dropmark. Biggest bummer is that images default to the thumbnail rather than the Raindrop tab.
