The Random Image Displayer will allow you to call on different images each time your page is reloaded and accessed. The Random Image Displayer consists of two files, the rand_image.pl and README.
1. rand_image.pl - The perl script that calls on the random image.
2. README - This file (Installation instructions)
|
|
This is the main file and the one that is called upon every time your page is loaded. You will need to place this file in your server's cgi-bin and give users the permission to read/execute this file. (chmod 755 or chmod a+rx) There are also several variables you will have to define:
| | |
| | Necessary Variables
|
| |
$basedir = "";
This is the http address and base directory that your pictures are placed in. This is in url form. The filenames you specify will be appended to this address. Examples Below.
@files = ("","");
These are all of your files placed into array. The filenames should be reflective of the location of the files relative to your $basedir. Examples Below.
|
| | Options
|
| |
$uselog = "";
You can enable the usage of a short log, which will simply log the name of each file as it is accessed. Not very fancy, but it can be useful.
$logfile = "";
The system path to your log file and where you want it kept. Keep in mind that this log file must be placed in a world writable directory. If you don't create a log file, but point the path to a world writeable directory and give it a false filename, the script will create the file for you. This is not a required variable if you turn off $uselog.

Let's say I have 5 files. The directory structure looks like:
/home/mattw/public_html/
pics/funny.gif
nature/waterfalls.gif
pics/cool.gif
nature/tree.gif
pics/www.gif
Where pics/ and nature/ are directories that these images are located in. Your variables should show as follows:
$basedir = "http:/host.com/~mattw/";
@files = ("pics/funny.gif","nature/waterfalls.gif","pics/cool.gif",
"nature/tree.gif","pics/www.gif");
|
|
This file can be used in your pages in one of the following syntaxes.
It can do backgrounds, or just plain image references. To activate it do the
following:
For a random in-lined image:
<img src="http://www.ser.ver/cgi-bin/rand_image.pl">
For a random background image:
<body background="http://www.ser.ver/cgi-bin/rand_image.pl">
|
|
|
If you are using it as a random background program, you will want to make sure that all of your backgrounds will work with the specified colors. In other words, if you have a dark and a light image in your random image path it will be hard to find a text color to work in both instances.

|
| Version 1.0 07/01/95 | - First Created |
| Version 1.1 07/17/95 | - Completely Re-written. Less variables to fill in, added flexibility: including pics in different directories and pics with names unlike others. A big improvement over the last version. You can also have different extensions like .jpg and .gif. |
| Version 1.2 07/20/95 | - Eliminated the $numfiles variable and can now take the random number straight from the array. |
