Optimizare,

Are you trying to call this code multiple times on the same page? If so, yes, it can randomly select the same number numerous times. When calling it more than once on the same page you will need to look into a more involved solution that keeps track of previously used images.

Mike,

It will take creating an array and looping through it randomly. If you are interested, I could make another blog post with an example that would accomplish what you are looking for.

Thanks Chad. Is there away to assign a a href link around each of those images and an alt tag unique to each image?

If you’re pulling the images from a database, you will need to use a combination of HTML and PHP to display them in that order.

Hi Chad, you’ve been a great help.
I’m building a animated “gif” hosting site, i’d like to categorize my images and have 4 of the most viewed images at the top of the page and then the newest stuff below.
I’d like to be able to find the gifs in pre-determined categories as well.
I’m savvy on using the divs or tables to space them i just don’t know what kind of code i need to write.
can i do this in html or will i need to use php?

Bruce,

You will either need to look into using a slideshow, or you can track user’s sessions. You can assign a session variable that keeps track of the last image that was shown for that particular user, and have the image change every time the page is refreshed in sequence.
