Hi Hartmuth
Hartmuth Kintzel:
I don't understand the limit of 2560.
It's not a limit, it's that AstroBin generates a number of lower-resolution images in order to serve them at various size. It would not be efficient to serve the original resolution image at full size, when it's going to be displayed at a smaller size.
These smaller resolutions are for the gallery thumbnail, the regular view with the technical card, and the fit-to-window view.
When these resolutions were decided, many years ago, nobody had 4k monitors like yours, even tho today they are more common, so 2560 pixels was the size that I decided for the fit-to-size large view.
I will add to my list a task to add a larger size too, to fit 4k monitors and ultra-wides, that will be generated on demand when needed.
At this time I cannot commit to a release date for this feature, unfortunately, due to the large number of tasks in my list.
Thanks for understanding!
