I have been using the Fancy ImageBar module since webtrees 1.7.x using a specific folder for portrait pictures. I currently have 36 .jpg files in that folder with all of them using the typical portrait format with an identical aspect ratio of 2:3. I am using the same pictures as primary media objects for these individuals.
Now with webtrees 2.0.11 and Fancy ImageBar 2.0.10 I can no longer opt out from the the square thumbnails. The only difference between the two options seems to be:
opt-in: a square cropping happens at the center and "scalps" the individual
opt-out: a square cropping happens at the top and cuts the individual's chin off
I consider this a bug and just opened
