Hi Marc!
I suggest making 'image/jpeg: inline' transforms clickable, like 'image/jpeg: link', to see the big pic.
Yes, all transformations need work. Currently, those are just dummy functions, a proof of concept. We should work on them after an initial bugfix phase (so...after now), when the main functions for reading/setting transformations is working without any problems.
So we should maybe open up a new request tracker item and put all wishs for transformations to there?
