Basics
In its basic function you can use Mirador to view digitized images. By using the scroll wheel, you can zoom in and out of the picture, with the left mouse button pressed, you can drag the image. On mobile devices just use pinch and zoom and drag the image with your finger.
The navigation bar below the image allows flipping through the pages, jumping to the beginning or end and selecting a specific image by scan number. Via the view menu in the upper viewer bar Mirador offers a number of views: You can choose between single view, book view or gallery. If the 'Book' view is selected, the view can be shifted by one image. A thumbnail bar can be optionally displayed below or to the right of the image or hidden completely.
Sharing and Posting
In the upper viewer bar the appropriate button offers the possibility to share links to digitized pages by e-mail, on Facebook, Pinterest, X or WhatsApp.
