This will output a random image, selected from gif, png, or jpg files stored in a directory at the top level of your site. The default name for the directory is random.
- download dca_random_image.gz
- unzip and put the .txt file somewhere handy on your computer
- make sure
use_pluginsis set to 1 in /lib/admin-config.php - go to admin -> plugins and use the form at the top to select the .txt file to install
- put
<txp:dca_random_image />on a template to try it out

Dean, there is bug in this plugin.
You have an array('gif','jpg','png'), but since array items are numbered starting with 0, the evaluation of isset($types[$type]) fails for PNG. The $type here needs to be decremented by one.

OK, I like this plugin because it allows me to simply use a symlinked dir from another Photostack site.
A little suggestion. If you extend the last condition before adding the file into the array by
&& array_search(substr(strrchr($file,"."),1),$types) !== false
it will only process files which have the right extension. This way, other files like HTML etc. get excluded straight away, avoiding a ‘not an image’ situation.

Some image editing packages will save an icon file that starts with a ‘.’; Graphic Convertor under OS X for example. When this happens the icon files get read along with the actual image but fail to display. The array_search added by mamash may actually solve this as a happy by-product though.

The array_search will only check if the file has a proper image extension. You might want to do another check on the first character. Or maybe having a single regex pattern would be more elegant.

True. I didn’t spot the extra ‘r’ in strrchr. My bad.

If you have the GD library installed, you can do this:
<pre>
$imageinfo = getimagesize(‘/path/to/image.jpg’);
if($imageinfo[ 0] > $imageinfo[ 1])
{
/* Width is greater than height */
}
else
{
/* Height is greater than width */
}</pre>

The method that erwin links to can be used for background images in a style sheet. It can even be easily modified to serve up random text.
