send_file, is this practical or is it memory hog?

hi, i was just wondering how resource heavy is send_file ?

i am protecting images in a site, outside a public folder.....when a visitor views an album, i check if that user is a friend, if so,  render the gallery. the rendering of the gallery basically just loops through a img tag that makes a call send_file to send the image to the page.

Yeah - I think this will indeed a resource intensive thing since this lets a user download a file while still being able to browse your site. It'll consume considerable bandwidth also if the file size is large.
