 ok that worked // there is a bug in the latex preview // it caches old, stale latex renders and reuses them inappropriately // to fix just enter lots of tex sections to flush out the stale images // and don't use latex + preview

Easier to clear cache or reload images. (I forget if that still works)

oh yes - they aren't using cachebusters on the image urls

super quick workaround = ctrl + f5 (force reload from origin)

I was unaware of that workaround, is it a Mac or a Windows trick? Is it browser-specific?

I see no reason to delete this thread, if it contains potentially useful advice like this.

AFAIK all browsers have this feature - what key binding they use I don't know

CTRL-F5 works on IE and FF for Windows

this option alters the HTTP request to force intermediate caching proxies to pass on the request (including browsers local cache)

the web master should alter the preview image URLs by adding a cachebuster:
