Best practice to prune new image cache?

[BigMike]

Hello SMF,

I recently upgraded our forum and am now using HTTPS + Image Cache feature. Using the default settings, after about a week our /cache/images folder now has nearly 20 GB (our forum size is 1.1 million posts, 23k members). We have tens of hundreds of large cached files (between 1 MB and 8 MB) so I've reduced the value for maximum file size to cache to 1028 KB and am wondering if I can just wipe out (empty) the entire cache/images folder save for index.php and let things re-cache now with the lower image size value?

I spent time searching for an answer on this so sorry if this has already been answered. The Wiki doesn't provide any details.

Moving forward, what is the best practice here? Empty the folder monthly or so? Thanks

Regards,
BigMike

Hey Mike,

Have a look at https://github.com/sbulen/sjrbTools/blob/master/proxy-maint-cron.php
Might be helpful to you.

Thank you Liroy, that worked excellent! I've configured it as a cron task that runs before the server creates nightly backups
