@NogDogJun 05.2005 — #Hmmm...looks like JavaScript. Did you mean to post this in the JS forum, or are you looking for a PHP alternative? @NogDogJun 06.2005 — #If what you're looking for is a different image each day, yes, it would be fairly simple with PHP. You would only have to change the html page on which this "random" image is displayed, renaming it to have a .php suffix instead of .html. Then you'd need a little PHP code where the image will go. Are all the images in the same directory? If so, you could do something like this:
@NogDogJun 06.2005 — #No, the idea I was proposing would pick out one image file from your image directory and display it at that point in the page. The images would still be .gif images. The only .php page would be the actual page on which the image is displayed (i.e. if it's index.html it would now be index.php).
You wouldn't have to list every possible image file in the script, it's reading the img directory and grabbing every file name in there. Then it's using the number of days since the "UNIX epoch" (the day that UNIX starts counting seconds from) to do a little math and pick one image name from the array to be displayed within the IMG tag.
The only thing you should have to do is change the '/img' value in this line...
...to whatever the correct directory name is for you images. (If you have non-images in that directory, we'll have to add a little more code to pick out only the image files.)
The whole idea here is that you don't have to change the script as you add/delete images files to/from the img directory.@NogDogJun 06.2005 — #This should (hopefully) pull out only the .gif and .jpg files from the current directory:

# select image number:
$imgNbr = $days % count($images);
# display image:
echo "<img src='{$images[$imgNbr]}' alt='Today's Comic'>n";
