Improvements to the thumbnail generator
One customer noticed these limitations of the thumbnail generator:
Square dimensions are used by default. This means that images with different widths and heights can vary greatly in quality when portrait and landscape images are used at the same time.
The media manager allows the width and height to be set differently, but thumbnails that deviate from this format will be of poorer quality.
In the customer's words:
A square display is rarely the case. The most common display is landscape format.
For optimal quality, the shortest side should be used rather than the longest side.
This is the only way to ensure that images are always (!) optimally used in the respective resolution and based on the srcset / sizes attributes.
