I too liked the look of this Dennis so I thought I'd try it out. Quick to get on site, and browse, however when I chose one of my pics it eventually came back with an upload limit of 1.5mb's and my pic was 2mbs.
This doesn't happen with image shack. Wonder if you've to do anything else first?
Tried Andavari's xs.to, (picture below) quick to site, same uptime load of pic as imageshack
