I love wide format for natural and lanscape photos. In this one I just cropped out the sky and reeds in the foreground. They added nothing!
Looks like wide format is ok through flickr just a bit tiny
This image was transfered using Hello and BloggerBot, and it did gives more control over the size. Both ways had the pictures posted on my blog within 1 minute. Which means they both definitely passed my "anything to reduce the tedious stuff" desirablity test.
