Resize Image?

[vexious]

I need some help, and i'm really not sure how to go about doing this. I have a script which will output images onto a page, however images uploaded are of all various sizes. I want all images to have the width of 200 but i want the proportions to be retained. How would i go about doing this? Here the bit of code that displays the image:

 

<div style="text-align: center; padding-top: 5px;">
                <a href="$appUrl?t=details&id={$row['id']}&author_id={$row['author_id']}">
                    <img src="$imageBaseUrl{$row['file_name']}" alt="{$row['tags']}" />
                </a>

$max_width = 200;
if($width > $max_width)
{
$height = ($max_width / $width) * $height;
$width  = $max_width;
}

 

That will give you the new sizes for images which are too large.

I also want it to increase the width of images less than 200 was my main problem. (I know it will look stretched but i need it to)

 

Basically I want all images width 200, and height doesn't matter, just proportional from the orginial size..

 

Not sure if this is possible really

 

example:

if the original Image was: Width:80 height:100

 

The image displayed should be:

Width 200; Height:160

Well, still (almost) the same

 

$forced_width = 200;
if($width != $forced_width)
{
$height *= $forced_width / $width; // just made it shorter, it's still doing the same
$width = $forced_width;
}

thnaks mate, one last question,

 

how would i put that code into:

 

<div style="text-align: center; padding-top: 5px;">
                <a href="$appUrl?t=details&id={$row['id']}&author_id={$row['author_id']}">
                    <img src="$imageBaseUrl{$row['file_name']}" alt="{$row['tags']}" />
                </a>

You could get the size of the image using getimagesize() and use the height and width HTML attributes on the img tag. You could also generate a new image with the new size dynamically at each request or you could one time generate a new image and store it on the server. It would be best to choose one of the two last options.
