XF 1.3 Image cache refresh questions

[Moddis]

1) If the date in Image Cache Refresh is greater that 7, when the refresh happens 7 days after the image was first successfully cached to forum and the image on the original server was already deleted, will it now cache and overwrite the good image on the forum with the broken image that's now on server?

2) Does that refresh only happen when someone access the page with image after the 7 days since cache time? So even if cache time is 7, it may actually not refresh image cache for much longer if nobody access the page with that image for months?


Thanks!

1. If the image hasn't been deleted from your server (the lifetime), then the last working version will continue to be used.

2. Images are only ever refreshed on demand.
