Just read the filenames from the directory and put them in an array,
then select a random element from the array.

please could you elaborate, i have done very little with reading dir's and array's

thanks

just use

-- imageArray[0]="image1.gif"; --
-- imageArray[1]="image2.gif"; --
-- imageArray[2]="image3.gif"; --

..etc and then to select a image from this array just write:

-- $randNum=rand(0,2); --

this rand() function will return a number between 0 and 2. In this case the array has indices 0-2 so this is waht we want.

Now just type

<img src="<? echo imageArray[$randNum];?>">

and you should be good to go.
