    Is this possible? View dynamicaly assigned images on a page

    I have a security camera program that, upon detecting motion, uploads via FTP the images to a web site. I can then view this web site using a web browser and it 'lists' the images, like a text directory in windows. To view one of these images I need to double click on the filename in the list.

    Each filename is created using YYMMDDHHMMSS format. so in one day I may get filenames as follows:
    081212090000.jpg
    081212090001.jpg
    081212101520.jpg
    081212121511.jpg
    etc

    Is there a way to create a web page to display all these images?

    If when the security program uploaded these images it named them 1.jpg 2.jpg 3.jpg etc then I could easily write a static page with images 1~100 say. As these were uploaded to the site these images would appear.
    However creating image names for all possible image names is impracticable I thought there must be some wildcard or smart system for simply displaying ALL images at a certain location, and this solution may be Javascript.

    How can I go about achieving this?

    Many thanks for any help.

    Javascript isn't your answer

    You could use a Server Side language to achieve 2 methods....

    a) Rename HHMMSS.jpg to "1.jpg" - you can then use Javascript to cycle through the Images.

    b) Use the server side script to get the contents of a file (in PHP it would be scandir, and then just create the images...

    Option b would certainly be the way to go... and the PHP would look something like this....

    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Image Viewer</title>
    </head>
    
    <body>
    <?php
    	$folder = "images";
    	$folderContents = scandir($folder);
    
    	foreach($folderContents as $folderPath) {
    		if(strpos($folderPath,".") != 0) {
    			echo("<img src=\"" . $folder . "/" . $folderPath . "\" height=\"200\" width=\"200\"/><br />");
    		}
    	}
    ?>
    </body>
    </html>
    Which will give you a HTML document such as this....

    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Image Viewer</title>
    </head>
    
    <body>
    <img src="images/awaiting_image.jpg" height="200" width="200"/><br /><img src="images/background.jpg" height="200" width="200"/><br /><img src="images/bullet.gif" height="200" width="200"/><br /><img src="images/close.gif" height="200" width="200"/><br /><img src="images/closelabel.gif" height="200" width="200"/><br /><img src="images/donate-button.gif" height="200" width="200"/><br /><img src="images/download-icon.gif" height="200" width="200"/><br /><img src="images/hori_loading.gif" height="200" width="200"/><br /><img src="images/image-1.jpg" height="200" width="200"/><br /><img src="images/loader.gif" height="200" width="200"/><br /><img src="images/loading.gif" height="200" width="200"/><br /><img src="images/nextlabel.gif" height="200" width="200"/><br /><img src="images/prevlabel.gif" height="200" width="200"/><br /><img src="images/thumb-1.jpg" height="200" width="200"/><br /></body>
    </html>
    (obviously your array will contain different filenames to mine )

    Many thanks for the reply. I tried the above and what I got was a page with just the following:

    "); } } ?>

    I have never touched PHP before but have played with Java, Javascript and Visual Basic plus other little scripting programs so I should be able to figure out how to mkae it work but cant

    The variable 'images' would this be a sub dir off the directory where the above page is to be created? Or will it look in the same directory?

    Many thanks

    Yes, it would be a sub dir off the directory where the above page was created...

    /randomnfolder/showImages.php
    /randomfolder/uploads/image1.jpeg
    /randomfolder/uploads/image2.jpeg
    /randomfolder/uploads/image3.jpeg

    etc....

    If im entirely honest... i'm not 100% sure what would lead you to only get that output... what version of php is installed on the server?

    I have the exact code....
    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Image Viewer</title>
    </head>
    
    <body>
    <?php
    	$folder = "images";
    	$folderContents = scandir($folder);
    
    	foreach($folderContents as $folderPath) {
    		if(strpos($folderPath,".") != 0) {
    			echo("<img src=\"" . $folder . "/" . $folderPath . "\" height=\"200\" width=\"200\"/><br />");
    		}
    	}
    ?>
    </body>
    </html>
    and it works fine on my server....
