OK so I found this script which basically puts text over an image so I dont need to create loads of images for my subnav. Here it is....

PHP Code:

<?
header('Content-type: image/gif');
$im = @imagecreatefromgif('_img/nav_link.gif');
$black = imagecolorallocate($im, 51, 102, 153);
$font = 'Verdana';
$text = strtoupper($_REQUEST['text']);

$box = imagettfbbox ( 6.4, 0, $font, $text);
$tw=$box[2]-$box[0];
$th=$box[5]-$box[3];
$px = (imagesx($im) -$tw)/2;
$py = (imagesy($im) -$th)/2;

imagettftext($im, 6.4, 0, $px, 12, $black, $font, $text);
imagegif($im);
imagedestroy($im);
?>

The only problem is that it doesn't work. My images are in the right place etc but it doesn't show up. I am using it here.

Any ideas????

Could be either one of the following:
- I think older versions of GD cannot save as GIF, try PNG or JPG
- I thought you had to upload the font file to the server and link to it in the script. Verdana is not included in Linux by default.
- Is your "nav_link.gif" file really in a subdirectory called _img? seems wierd to use an underscore like that
- Perhaps you have to reference locations local PATH (ie /var/www/blah/img/rar.gif)
- "imagedestroy($im);" sounds like you are making the image, then destroying it? you really should save the image, instead of making the script create it each time the page is loaded.

try commenting out "header('Content-type: image/gif');" then viewing the script maybe it's giving you an error that might help you out.

Well I got the script off a friend and it seemed to work for him. Yes I use an underscore (_) for all my image/include directories, wwhats wrong with that?! lol.

Thanks for the help anyway guys.

I'm sure your problem is PHP is not finding the image(s) in that location.

$im = @imagecreatefromgif('_img/nav_link.gif'); 

And why is there an @ in front of the function call? The @ is to hide or prevent the function call from generating an error. you should really check if the file exists using file_exists() rather then preventing the error.

change the first few lines to this:

PHP Code:

//header('Content-type: image/gif');
$im = imagecreatefromgif('_img/nav_link.gif'); 


then visit this link and you shuld get an error message that will help you out.

OK so now I get an error, but no idea what it means though. lol. Im crap with PHP!

[Larixk]

well, post it here.

<img>The image “http://www.publicwebserver.com/nav_link.php” cannot be displayed, because it contains errors.

It was something different but I've been away again because my PC broke so I got a new one. :p

Do this and you should get something more informative.

That way when you look at the root in alphabetic order, naming something with a preceding underscore will force it to appear at the top of the order. Some people do that, like...

"/_css/"
"/_images/"
"/_scripts/"
