I always document our project via markdown. In case I need to attach a screenshot, I always go to my local phabricator setup, open a temporary *create task* window, paste an image into the textbox to get an image ID, something like {F3004}. Then I place this string into the markdown text. Once done, I commit to the svn server. The phabricator can later display the documentation as well as the images so my team could read.

Recently other team members told me that they never saw images posted by me, they only see things like:

While I can view those images with my account, like this:

I then tried the following:

• I logged into their computer with my account. I can view the images.
• In my computer, I logged in using the admin account, still cannot view the images.

So it is not related to computers or browsers. It is only related to user accounts.

Is it a bug?

[Update]
I upgraded phabricator just now to this commit:

The problem still persists.
