[RESOLVED] What is needed in HTTP header to output a picture

[Mgccl]

Like what is the least requirement so it can show in browsers? because when you just use

readfile('haha.jpg');

it shouldn't work as a JPG file but milions of characters.....
so like you got to put some HTTP header like "Content-Type: image/jpeg"
does it reqire anything more than that like the size of that that file? or it's only needed when you are outputting more than just a jpg file?

[planetsim]

It only requires the Content-Type: image/jpeg assumming that it is a jpeg file being sent to the client.

The only time you need to specify things like filename/filesize would be if you're sending headers to get the browser to download the file as an attachment.

For displaying purposes, you only need the correct Content-Type header as planetsim pointed out.
