feature: enter ratio manually #28
Description
This is similar to #18
It would be great if the user could enter an image ratio manually. And optionally the current/original ratio of the images would be displayed. This would allow users to adjust, for example, all landscape images to use one common ratio.
Right now, as far as I understand, I could only use one ratio for all images, and this ratio isn't selectable by the user. With this feature the user could user their own ratio and also decide to have different ratios in one gallery (e.g. one for landscape, one for portrait).
