display image smaller on webpage

leena

Hi guys,

I have looked all over, and have found few things on this topic but unfortunately I still don't know what I am doing.

What I am doing is having people upload pictures, and then I will print off cards. These cards need to have the picture on them that those people uploaded. However I want them to display as a certain size.

I don't need to resize it as they are uploading the picture, and I don't need to resize the picture in the directory they uploaded it to. I need to take that picture (whatever size it may be), and just display it as a smaller size. Does anyone know how to do this?

Thanks so much for your time. Any help is greatly appreciated. Even if you can just point me to a specific page to read.

I tried:
function LoadJpeg ($imgname) {
$im = @imagecreatefromjpeg ($imgname); / Attempt to open /
if (!$im) { / See if it failed /
$im = imagecreate (150, 30); / Create a blank image /
$bgc = imagecolorallocate ($im, 255, 255, 255);
$tc = imagecolorallocate ($im, 0, 0, 0);
imagefilledrectangle ($im, 0, 0, 150, 30, $bgc);
/ Output an errmsg /
imagestring ($im, 1, 5, 5, "Error loading $imgname", $tc);
}
return $im;
}

However it doesn't display anything. It doesn't get past the line:
$im = @imagecreatefromjpeg ($imgname);

Also I tried:
$src=ImageCreateFromJpeg($image);
$swidth=ImageSx($src);
$sheight=ImageSy($src);
$dwidth=$swidth.25;
$dheight=$sheight.25;
$dst=ImageCreateTrueColor($dwidth,$dheight);
ImageCopyResampled($dst,$src,0,0,0,0,$dwidth,$dheight,$swidth,$sheight);
ImageJpeg($dst,$thumbname);
ImageDestroy($src);
ImageDestroy($dst);

And then I got this message:
"<b>Fatal error</b>: Call to undefined function: imagecreatefromjpeg()"

I am using PHP version 4.1.1

Does anyone know what is going on?

if it's just a one off and your not bothered by slow downloading or a slight deformation, then you could just call the html and use the height and width commands to resize it:

if you only define one then it will automatically adjust the other to keep it in proportion.

Alternatively, just do a batch job in photoshop to resize all the images in a folder to a certain size and save them under a different name.,

and if you're getting that error it sounds like you havent enabled your gd library in php.ini
