Hello

sorry for post mistake.

‘preview_max_x’ => 100,
‘preview_max_y’ => 100,

i already change to

‘preview_max_x’ => null,
‘preview_max_y’ => null,

but the result still the same

Do you mean this preview?

I think the problem is the size of the picture.
The preview gets only the middle of your picture

I think the bigger problem is that you image is only open from top to button in the browser (nextcloud user and public sharing my link above) without scrolling.
In this nextcloud forum (your image -> https://help.nextcloud.com/uploads/default/original/3X/c/f/cf5af91b55731c7805c2bcfe32d53449f4a9d47b.jpeg ) the image is bigger and better. Perhaps a bug or issue for the photo app?

For other people: Perhaps “Sharing Path” can help to show direct the original picture and zoom and scroll in the browser.
