Well, I'm not sure who the culprit is, but I just did a test with two photos that I rotated in shotwell and uploaded to craigslist. For one photo all I did was rotate it. For the other photo I rotated and cropped it. The cropped photo displays as expected (in my browser) while the non-cropped photo has the wrong orientation.
My browser is firefox 3.6.17 Here's the craigslist post: http://boulder.craigslist.org/fuo/2381631631.html Bryan P.S. I'm not really trying to sell those bookshelves. This is just a shotwell test ;) On Tue, May 10, 2011 at 1:08 PM, Jim Nelson <[email protected]> wrote: > There's some confusion here about how Shotwell rotates photos when exporting > or publishing them.
