if thats the case, why not generate one more random number ?

<?php
	$arr=array();
	for($i=0;$i<7;$i++){
		$arr[$i]="./img/images/".$i.".jpg";
	}
	$random=rand(0,6);
	$random_1=rand(0,6);
		echo "<img src=".$arr[$random].">";
		echo "<img src=".$arr[$random_1].">";
?>
<?php
	$arr=array();
	for($i=0;$i<7;$i++){
		$arr[$i]="./img/images/".$i.".jpg";
	}
	$random=rand(0,6);
	$random_1=rand(0,6);
		echo "<img src=".$arr[$random].">";
		echo "<img src=".$arr[$random_1].">";
?>

This will do.. Don't you think ?

Ignorance is definitely not bliss!

that looks like it could do the trick with abit of working... basically....

i want there to be a folder of images... the names of those images could be anything at all.... number letters.. mixtures... there will be no logical order to them..... i just need the code to randomly pick say 10 images... out of that folder... no image being displayed twice etc...

if there isnt enough ... say there is 4 images.. it will just display 4

if there is no images... maybe just a statement showing there is no images to display at this time...

Hi, I am fairly new to web design and am trying to do exactly what you helped the other person on this post do, is there any way I could also get ahold of that code? I would be very grateful. Thanx.

This is something I just typed up. Not the same as the one I get to the other poster, but close.

It will read a folder and get the images. Then randomize them and display in a paginated form.
