How to use the PIXLR editor on Google Drive images

I am trying to use an editor in Google Drive images — the PIXLR editor —, but is giving me errors as shown in the screenshot below.

I had an image which when I wanted to open

In last screenshot you can see I get a 404 not found error and this is not only for this image. Any screenshot which I want to open with this app in Google gives me this 404 not found error.

Any idea why this is happening?
