changing pictures by number

[flemingmike]

hi all,

 

quick question...  if i have 5 pictures pic1.jpg, pic2.jpg, pic3.jpg, pic4.jpg and pic5.jpg and im viewing pic3.jpg, is there an easy way to make a left and right button to scroll through the pictures by adding or extracting a number?

 

thx.

you could make a variable

 

pic3

$i=3;

$next =$i++;

$prev =$i--;

 

then echo $i

[greatstar00]

<a href="pic.php?pic=3&act=previous">Previous</a>

take the above as example

pic=3, the current pic, and act is the action u doing, forward of backward

 

if($_GET['act']=="previous")

echo "pic".(--$_GET['pic'])."jpg";

Sure, but what if you would delete a picture?
