TLJH software is in beta.

One of bugs is that it is not possible from user account to change image. i.e. if you choose 'jupyter/datascience-notebook:r-4.1.3' and then would like to switch to different image it is not possible.

Workaround is, that in case you would like to use different image request for new account.
