I already have auto-refresh on the page and this is not a problem on "real" browsers - just on the mobile devices. Again, I have a workaround in place, but was just looking for other (better) solutions.
I skimmed through multiple hits on this problem over at stackoverflow and most point to this same "cache-busting" fake query parameter to the img src tag. The real solution here should be to use unique filenames, which understandably won't work for everyone (e.g. not using the rsync delete option), but would be better in my situation so that the cache can be properly used for the less-frequently updated images. Sounds like a good project to avoid the family over the upcoming holiday. ;) -Chris On Fri, Dec 9, 2016 at 10:52 PM, Andrew Milner <[email protected]> wrote: > Images should be reloaded when refresh button is pressed in the browser if > they have been updated whilst browser is open on the page.
