Create dynamic images with the GD library. Tutorial shows you how to create a little man holding a sign that displays various messages (such a visitor's IP address and user-inputted text).
Many people have asked how I have my forum sig change automatically. It changes whenever a new tutorial is added to my site. You too can promote your site this way. You can also use the techniques discussed here to create any dynamic image. The sky is the limit.
A lot of forums won't allow PHP files to be posted since they *DO* pose a security risk. Here's a simple way around this. If you have the ability to use your own custom .htaccess file in a folder on your webserver, create it and add the following lines:Files *.pngForceType application/x-httpd-php/FilesSave the file, and place your php files in that folder. Then, just rename your file from *.php to *.png (just the script file you want to post). Then, just post the file in the forum like you would any other picture. The .htaccess will be run and according to my example, the png file that is being called, will be processed like a PHP file and execute. Works great for PHP GD images or for other scripting tools like the "Your IP address is" tool. -- That's how those other guys do it. Enjoy!
The BP Developments: Gallery, is made in PHP. You need to register before downloading.The first thing to do, is to register, then press on the download-link. It will then be e-mailed to your account. Upload the file, run it, and follow the instructions!Now version 2.0!
the goal of this tutorial is to give the reader an idea of how to construct a basic/dynamic image gallery from start to finish, not to imply that this is the only way, or even the best way to build a gallery; just a simple approach without all the bells and whistles. at the time of writing, this tutorial assumes a version of PHP = 4.3 and GD 2.
I'm sure many of you have logged on to Yahoo!, eBay or even here on hotscripts.com and have run across the verification image containing numbers and letters that you must plug into an input box for verification. And maybe you thought, "What the heck is this for?" or "I wish I knew how to do that." You wanna know--then I will show you how.
Depending upon how it's done, displaying a page of thumbnail images can be very cumbersome. Allowing the browser to resize images requires the client browser to download the entire, full-size image, then clumsily resize the image to a specified size. This causes the page to load very slowly and creates unavoidable distortion in the resulting images. The other option is to make separate thumbnail images for each individual image. This is fine if you only plan to display a few images, but becomes unrealistic on a large scale or a site involving dynamic images. Fortunately there are ways around these problems using the GD library in PHP.
