Readers have the option to click on an image, using the plus-sign. The UI tries to enlarge the image. However, in case of large images (esp. if the image is narrow yet tall, e.g. 1320 x 5532), it doesn't enlarge at all.
Can there be an option to enlarge pictures using a slider or an increase / zoom percentage, besides the current plus-sign option. Obviously, when zooming into a picture, parts will end up outside the user's screen, but that is fine, as long as the picture can be moved.
Something similar to how PDF files can be enlarged in Chrome.
Basically we're asking for a real image zoom function. Thanks for considering!
