[SOLVED] can I make my thumbnails links??

[php_beginner_83]

Hi Everyone

 

I'm trying to create thumbnails, using the gd library, on the fly.  I was wondering if it will be possible to have these thumbnails be links.  I'm not sure if this can be done or should I just create and save the thumbnails.  I know this way I'd be able to make them links.

 

This is my code ...

 

$filename = 'images/alcatraz1.jpg';
$thumbWidth = 50;
$thumbHeight = 50;

// load image
$img = imagecreatefromjpeg($filename);

// get image size
$width = imagesx($img);
$height = imagesy($img);

// set size of thumbnails
if ($width > $height)
{
$newWidth = $thumbWidth;
$newHeight = $thumbWidth * ($height/$width);
}
else
{
$newWidth = $thumbHeight * ($width/$height);
$newHeight = $thumbHeight;
}

// create temporary image
$tempImg = imagecreatetruecolor($newWidth, $newHeight);

// create the thumbnail
imagecopyresampled($tempImg, $img, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);

// output thumbnail
imagejpeg($tempImg)

By on the fly I assume you mean something like:

 

<img src="thumb.php?image=something.jpg&width=100&height=100" alt="" />

 

? If so, and you wanted to link them to the original image you could just do:

 

<a href="something.jpg"><img src="thumb.php?image=something.jpg&width=100&height=100" alt="" /></a>

Thanks AlexWD.

I'm trying to loop through an array of images and am having problems getting it to work...any ideas?

 

Thanks

 

While (...........)

$currentImage = "images//" . substr(strrchr($row['Path'],92),1);

   $counter++;
   
   if ($counter % 3 == 0)
   {
   		
	  echo '<a href=#><img src="shannaThumb.php?image=\"$currentImage\"" alt="" /></a><br/>';
   }
   else
   {
	  echo '<a href=#><img src="shannaThumb.php?image=\"$currentImage\"" alt="" /></a>';

   }

It would be nice if you were a little more specific, and if you showed us the array of images, would be easier for us to tell you how to set it up.

 

Right away though, I see this:

 

$currentImage = "images//" . substr(strrchr($row['Path'],92),1);

Is that supposed to be images/ with only 1 '/'?

[php_beginner_83]

I've had to use 2 '/' in other code because 1 didnt work so I figured I would do the same here but I have tried removing one and the code still didnt work.

 

My array of images comes from a database of images.  This is my code

I'm trying to take each image from the database and create a thumbnail and then have each thumbnail be a link.

 

Thanks for the help.

 

$result = mysql_query("SELECT * FROM pictures 
INNER JOIN pics_in_albums 
ON pictures.ID = pics_in_albums.PicID 
INNER JOIN albums 
ON pics_in_albums.AlbumID = albums.ID 
WHERE albums.ID = 1") or die(mysql_error());

$paths = array();

$counter = 0;
//fetch tha data from the database
while ($row = mysql_fetch_assoc($result)) 
{

$currentImage = "images//" . substr(strrchr($row['Path'],92),1);

   $counter++;
   
   if ($counter % 3 == 0)
   {
	  echo '<a href=#><img src="shannaThumb.php?image=$currentImage alt="" /></a><br/>';
   }
   else
   {
	  echo '<a href=#><img src="shannaThumb.php?image=$currentImage" alt="" /></a>';

   }
   
}
?>
