I think this discussion link of a thread before would be helpful. https://bitcointalk.org/index.php?topic=388403
theymos replied there about the issue.
PS. It happened to my post before, Idk but it sometimes occur and be fixed without changing anything   While sometimes the problem is the image/image link itself

EDIT: I saw that your problem is with the Indahash translation. You're using an invalid link. It should be an image link, with .jpg .png extension

You need to get the direct link of your uploaded image and not any shortened URLs. Usually ends up with the file extension .jpg, .png, and .gif depending on what file type it was saved prior to the upload. Also bitcointalk sometimes blocks off images uploaded using a site it deems insecure, though the case about this is very rare.

I think this issue regarding to the the Shortern url.and chexk whether your image hoster support with bitcointalk.
