Subject: Keep local cached images fresh if file exists.
X-Git-Tag: 16.3~129^2^2
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=4a27966e78407d4482de5d1a70093930f9eb8b85;p=tt-rss.git

Keep local cached images fresh if file exists.

Updates the cache_images() function to `touch` images if the file exists already. Some sites (e.g. news) re-use stock images and this change updates the local file's modified time every time the image is referenced in new articles. This should prevent the local file from being expired/deleted only to be re-cached later on.
