It really bugs me to see the landscape pictures in the Online Gallery displayed in the wrong orientation. I’m sure it bugs everyone else also. I’m going to work on the web site end of this and rotate the current landscape pictures manually. The next release of OmniSketch will have the ability to set a picture for landscape view. Then you’ll see you pictures in the correction orientation both on the iPad and online in the gallery, Twitter and Facebook.
I’m also working on making the App universal so it will run on iPhones and iPods as well as iPads.
