[RESOLVED] readfile v <imgsrc>

[ianc4ever]

using php5/mysql5/vista

ok, in any html or php page we can use imgsrc to display an image.

Why do we need to use readfile() and send header info whenever the imgsrc way doesnt need image headers to be sent?

Im talking bout when it comes to displaying images as opposed to any other type of file which i know <imgsrc> cant open.

What r the benefits of NOT using <imgsrc> method to display images?

much apprec
php newbie

Who ever said that using an <IMG> HTML tag doesn't require the same image headers as displaying the image from a PHP script?

Whenever your browser encounters an <img> tag, it makes a separate request to download the image referenced in the "src" attribute. This separate request has a separate set of headers (e.g. "Content-Type: image/jpeg") since it's a separate request.

How else would you display an image, then, if not using an <img> HTML tag?

hmmm,
makes sense, i learned something today.

I thought one way was proper method to display an image and other was...magic.
