title: moving wordpress blog to new url - gallery images sizes broken
body: <p>I moved my old site <a href="http://traumbad-muenchen.de/referenzen/" rel="nofollow">http://traumbad-muenchen.de/referenzen/</a> to a new one yesterday:
  <a href="http://bodenmanufaktur-muenchen.de/referenzen/" rel="nofollow">http://bodenmanufaktur-muenchen.de/referenzen/</a></p>
  
  <p>On the mentioned page you can see that the added gallery (traumbad-muenchen) shows images in the same size BUT the gallery on the new site (bodenmanufaktur-muenchen) shows images with different sizes, which looks strange.</p>
  
  <p>I posted the exactly same code in the new site, but nothing is changing.
  I also noticed that I can`t upload new images at all since yesterday to the media libary.</p>
  
  <p>Does anybody know why this bug appeares and how I can change it?</p>
  
  <p>Thanks
  BR
