Hello Vivid Group,
Sorry for the inconvenience with the "." bug. The good news is that our new release is coming.
To upload a picture you need to have a valid user name. Remove the "." from the user name, upload the picture and save the changes.
Then go and add the "." from the sql management studio. Check that the image column is not changed.
After that you should see the image for that user.
