[Insight-developers] Need to add images for new tests to Data -- how to do that in a Gerrit topic?

[Bill Lorensen]

Please keep the process as simple as possible. We need to encourage testing.

My preference would be to move the Testing baselines into the main
repository, just like it was before.  Adding a baseline should be as
painless as possible. The Testing data can reside somewhere else, but,
as Kent said, it should be downloadable all at once to allow testing
without an internet connection.

I think the current setup is too complicated. Actually, I don't understand it.
