I've searched the archives with no luck for this issue.

When a given skin doesn't change the filename for the graphs (day*.png,
etc.) the images are never updated/reloaded when viewing on mobile browsers
(tested Safari & Chrome on an iPhone).

My workaround was to append '?$current.dateTime.raw' to the img src. The
minor downfall with this is that for the images that are not updated every
report cycle (weekly/monthly), since the html file is still regenerated,
the current timestamp will still be appended. Granted, since these images
are so small, it's not much to worry about.

Are there any better fixes for this problem? Given it's impossible to know
which browsers will obey any of the Cache/Pragma/Expires parameters, maybe
there isn't...

Thanks!
