Have you by chance been having trouble with images showing up in other posts as well? I have... I don't know if it might have anything to do with this post being posted with the Android app, Steemia (possible using a different file storage location). Yesterday after I uploaded the post, I could not see the picture either, but today it seems to be working for me. Maybe I should try editing the post and replace the picture using either Steemit.com or Busy.org.
