Nginx How can i exclude an image from Nginx cache?

nginx doesn't caching anything out of the box even for centmin mod nginx. So if you have setup nginx caching mechanism, you'd have to exclude it depending on what you setup

if you mean browser level caching via cache control headers, then just setup a location match for that image and set different cache control headers to exclude it from /usr/local/nginx/conf/staticfiles.conf include file's default image browser caching
