I recently was uploading a few pictures to a Piwigo photosite I made and notice some did not display. after checking more I found these same photos wont open in Adobe photoshop or Paintshop Pro or Infranview but will open in microsoft photos or paint or paint.net. Resizing them or converting them to another format like bmp seems to carry over the same problem. I discovered that for a few of them I have originals that display fine on everything but I dont have all the originals. I am trying to figure out not just why this happens but is there a software that can repair them ?
