Mobile browser - cannot pan a zoomed photo

[miahi]

Detailed description of the problem [REQUIRED]

Browsing on mobile allows zooming on a photo page, but that zoomed photo cannot be panned and the onclick event is triggered (upper menu disappears).

Steps to reproduce the issue

Steps to reproduce the behavior:

1. Android browser (Firefox/Chrome/Samsung Internet), access a photo
2. Pinch to zoom (max zoom)
3. Try to slide to pan
4. The photo will zoom in and out a bit for each pan trial, as the upper menu is shown or hidden (off screen), but it will not pan

Any comments on this? Most people use their mobile phones to interact with web these days. Sadly Lychee photo viewer is not optimized for mobile browsers.

We are a very small team and developping on free time. I do agree that adding such feature would be great, unfortunately it is not a priority too. For now the best I can is put it as "Project for volunteer".
