PHP, or PHP Hypertext Pre-processor, is one of the most popular scripting languages available to web developers. There are many reasons why PHP is now the most popular server-side scripting language for the Apache web server. Firstly, it supports database connectivity to a huge number of popular vendors, including Microsoft, Oracle and IBM. Secondly, with the correct libraries installed, PHP also supports real-time generation of images, PDF files, and even shockwave movie files! The only limit that bounds us when we’re developing with PHP is our imagination.
For developers like myself, one of the most popular features of PHP is real-time image generation. That is, we can create a new image canvas, “paint” it, and either save it to a file, or send it directly to the browser. In this article, I will show you how to create an image in real-time with PHP. The image will be similar to the ones used on yahoo.com and paypal.com, where a random number is generated inside of an image. That image is displayed in the browser, and you have to enter that random number into a text box to create a new account. This is a method that is becoming more popular, and it’s used to stop people from generating multiple user accounts in one go, which, is some cases, can crash the web server(s).

This thread is for discussions of Image Generation on the FLY using PHP.
i want to display an image on a form when an item is selected from a ComboBox. the image will be stored on the a:\drive (floppy). there will be multiple items in the combobox, each 1 relating to a specific picture. i just need the basic code to get the img to appear after selecting the item from the combobox. if n e 1 could email me the code or tell me where to get it, that would be great! oz_utester@hotmail.com

To my knowledge it is not possible to send an image created on-the-fly using PHP without the content-type header being modified. Why do you not want to use the "Header("Content-Type: Image/jpg")" code?
I think your posting in the wrong place buddy! this is for creating and showing PHP images on-the-fly not VB! If you DO really want to take a PHP created image and put it in a VB form you can either post back here or email me at webmaster@isgeeky.com
hi:
I copied your code to my PHP4.3.x+Windows2000Server+Apache2, The picture does not show at a browser, only white page. I checked the sapce befor the "<?php" carefully.
In fact, befor I have a similar bad experience that I can't show picture at my machine. But If I put the code to a linux machine , it works. The situation is all my other php codes, including session,mysql, work fine. Only for this method, header(header("Content-type:image/jpeg"), the send out a image, it does not work.
I guess there must be some setting parameters problem at apache2. Does anyone have any idea?
Thanks
thanx 4 ur time!

very well-written & useful javascript:smilie('

I used the script it was good. The random script is accessed as an image in another script, then how to access the number displayed on the image so that i can check that the user entered the correct displayed number.
Very good tutorial and useful. But am wondering, if it can be converted to be used as a counter in a website, to get the number of visitors to the site. It will then start from a certain number and count sequencially upwards. It could start from 1 or 10.
Thanks
Hi
I saw them using a image-on-the-fly script as (at www.worldspaceasia.com):
<a href="modules.php?name=Content&pa=listpagescategories&cid=2"><img src="includes/img.php?title=Western Classical/Jazz&textsize=8&border=1&imgype=randomTTF" border="0" alt="Western Classical/Jazz"></a>
The :
title=
imgype=randomTTF
are crucial!
So whts the secret of the img.php?
Regards
