External Pictures Load

If you want to use a PHP script to display your images out of a single folder - here's one that I quickly wrote for you. Let me know if you have any questions about it. Whatever you name this file should have a .php at the end of it so that the php executes properly on the web server.:

<?

////////////////////////////////////////////////////////////////

////////THIS IS A PHP GALLERY SCRIPT FOR A SINGLE FOLDER////////

///////custimize by changing the top three variables////////////

//and the bottom display values - nothing else needs to change//

////////////////////////////////////////////////////////////////



//This can also be an absolute path e.g. /var/www/yourwebsite/htdocs/images

$your_image_directory="images";

//the url of the images folder

$absolute_path_of_directory="http://www.whatever.com/images";

//whatever you name this file

$name_of_this_file="myimages.php";







//opens the directory

$dir = opendir($your_image_directory);

//will store the files in the directory

$files = array();

//looks through the folder

while(($file = readdir($dir)) !== false){

	//if we found a file

	if (is_file($your_image_directory."/".$file)){

		//get size of the image for filtering purpose

		$size=getimagesize($your_image_directory."/".$file);

		//if the size of width and height is more than 1

		if($size[0]>1&&$size[1]>1){

			//it's an image

			$is_image=1;

		//or else

		}else{

			//it's not an image

			$is_image=0;

		}

	//or else

	}else{

		//not an image

		$is_image=0;

	}

	//if we found the file is an image

	if($is_image){

		//put the file in the array

		$files[]=$file;

	}

}

//close the directory

closedir($dir);





//first file in array

$im=0;

//checks if we have an image request

if(is_numeric($_REQUEST[im])){

	//if we do make it the current image

	$im=$_REQUEST[im];

}





//if the image is 0 or the first image

if(!$im){

	//make the previous image the last image in the array

	$prev=count($files)-1;

//or else

}else{

	//make the image the previous image in the array

	$prev=$im-1;

}





//if we've reached the end of the array

if($im>=(count($files)-1)){

	//make the next image the first image in the array

	$next=0;

//or else

}else{

	//make the next image the next image in the array

	$next=$im+1;

}







?>

<center>

<? // DISPLAY THE IMAGE IN AN IFRAME OR WHATEVER ?>

<iframe src="<?=$absolute_path_of_directory?>/<?=$files[$im]?>" 

width="200" height="200" style="border:0px;"></iframe>

<br><br>

<? // PREVIOUS BUTTON ?>

<a href='<?=$name_of_this_file?>?im=<?=$prev?>'>[ < < Prev ]</a>

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 

<? // NEXT BUTTON ?>

<a href='<?=$name_of_this_file?>?im=<?=$next?>'>[ Next > > ]</a>

</center>

are you looking to cycle pages when page is visited, or whilst page is loaded?

If you are looking to cycle differnt images every time a page is visited... ie you go to http://www.yourdomain.com and a picture shows, but next time you go to the same page, there is a different picture showing, then you can do this in dreamweaver. there is a nice tutorial form another thread here:
http://www.elated.com/articles/fun-with-random-numbers/

If however, you are looking to cycle images whilst you are on a page, this needs to be done via another route. A Flash movie would be my preference. You then embed the flash movie in your page.

This is not a Dreamweaver script. It is a PHP script that can be inserted into a PHP web page.

If you want to use this on your page you will need to name your page with a .php extension so that the server parses PHP.

Secondly view the source code of the file and paste the code into your page in the location of where you want your image to rotate.

Thirdly you will need to define the 3 variables in the file:

$your_image_directory="";
$absolute_path_of_directory="";
$name_of_this_file="";

Put up a test page and try to make it work in the test page before putting it in your live site. Let us know if you have any questions.
