Allow Cross-Domain Images with CORS Images are usually cool to serve from a different domain but if you want access to their data with canvas, you're in trouble. This snippet allows you to get raw image data via canvas:

.htaccess - Allow Cross-Domain Images with CORS.htaccess

<IfModule mod_setenvif.c>
    <IfModule mod_headers.c>
        <FilesMatch "\.(cur|gif|ico|jpe?g|png|svgz?|webp)$">
            SetEnvIf Origin ":" IS_CORS
            Header set Access-Control-Allow-Origin "*" env=IS_CORS
        </FilesMatch>
    </IfModule>
</IfModule>
