Some initial feedback:

  * Title Case Everywhere Looks Weird  
  * Hovering over 'resolution' on the detail page shows a tooltip with the text 'Upload date'  
  * I uploaded a .NEF file and it seems to think it's 160x120 (it's actually 6000x4000)  
  * The buttons next to the link field on the detail page are not the same height as the input.  
  * When uploading the background icons become jerky (presumably due to the upload causing long frames)  
  * When uploading there was no speed / ETA data shown, just a spinner.  
  * I felt the animations on the homepage were all a little superfluous.  
  * The links in the footer link to places on the page, but without updating the URL hash, probably worth adding one to make it more linkable.
