Description
Initial Checklist
- I understand this is a user story and questions should be posted in the Community Discussions
- I searched issues and couldn’t find anything (or linked relevant results below)
User Story
- As a user I want the photo roll of the preview app to have a good performance so that it doesn't slow down my browser / device.
User Value
Fast UI
Acceptance Criteria
- for the images in the photo roll of the preview app, introduce a "loader"-div (skeleton loader) like we do it in the files app, which gets replaced with the actual image when it scrolls into the viewport
- request a smaller resolution for the images in the photo roll, so that we don't cause heavy memory load in the browser (use the same resolution as for the tiles view... if the user comes from the tiles view, best case is that the images are already cached server side and fetching them is fast then... and they might even still be cached in the previewService so that we don't need to fetch them at all)
