PHP: Internet: Web: Server: Image: How to send an image from the web
server to web browser client?
Use the MIME type to inform the browser about what
is going to be send.

Steps: Overview:
1. -Before you send the image, print the text:
Content-type: <your text type>
---
e.g.
Content-type: text/html
---
e.g.
Content-type: image/gif
---
e.g.
Content-type: image/jpeg
---
e.g.
Content-type: image/png
---
e.g.
Content-type: image/vnd.wap.wbmp
---
---
2 methods to display the image file in your web browser:
1. use the filename as the source (SRC) in an <IMG> tag
2. display the content of the filename
---

Method: use the filename as the source (SRC) in an <IMG> tag.

// shows a picture via printing HTML code
$filenameS = 'fotoknud.jpg';

=150 ISMAP ALT=' . "'" . '[picture: knud]' . "'" . '>';
?>
