Shashin and prettyphoto work great on a standard monitor, but on my phone (Google Nexus 5, 1920x1080 screen, chrome browser) I don't get the popup photo overlay when I click on a photo thumbnail. The phone's browser window dims, just like it does on a full size screen, but there's no top window with the photo.
In a 5-month old response to someone else's question, you mentioned possibly switching to lightbox. Is that still the plan?
Nice plugin, mike, works well.
