In my one of my Content Type, I have used File Field Sources and set an Image field to work as to insert Images thru:

  • uploading
  • browsing server and
  • attaching file from server (last two thru IMCE file browsing)
  • enabled IMCE file browsing settings permissions

However, when I go to the content and try to upload an image via file browsing and selecting existing image from server, it does not seem to work (being able to browse server files via IMCE file browser, but inserting selected image does not work or load):

Fix / What works

  1. Ensure you have the following modules installed and enabled:
    • File Field Sources
    • IMCE
    • IMCE for File Field (this one you would normally miss)

  1. Make sure user profile has permission to use IMCE and IMCE File browsing (Administration > Configuration > Media > IMCE > Edit selected user profile)

     
  2. Go back to you Image field in your content type (Structure > Content Type > Image Field > Edit > Check “Allow users to select files from IMCE File Browser for this filed.”
  3. While on this setting, allow also Full Browsable directory

It will now have an additional fiel browser selector (magnifying glass icon) and browsing and selecting file working

Hope this helps!
