I've a picture blog, someone is fetching my image from server to his server, via remote image fetching script etc; (eg; Upload Image from URL like script) how can I prevent this?
That's called hot linking. If you're using apache, an addition to .htaccess can stop that. Basically if a request has an HTTP referrer, you don't serve the image, or serve up an alternative image, such as your blog name and logo.
Im using .htaccess to prevent hotlinking and its working fine, but tell me does .htaccess prevent image fetching via upload scripts?
