Manipulating called image size?

dragon5

Hello, I'm having a hard time figuring out how to control the size of the images called by the following piece of code.

<?php
if (tep_not_null($product_info['products_image'])) {
?>
<table border="0" cellspacing="0" cellpadding="2" align="center">
<tr>

</td>
</tr>
</table><br>
<?php

The image is currently displayed full size and i need it reduced it by at least 1/3. Should be a way to integrate the html parameters of height & width to control size. Any help would be appreciated.
Thanks
Tom

<?php
list($width, $height, $type, $arr) = getimagesize(DIR_WS_IMAGES.$product_info['products_image']);

// Set the max width/height to 1/3 the size
$nwidth = round($width/3);

// Create proportionate height/width
$nheight = ceil($height*$nwidth/$width);


if($height>=$width){
    // image is tall, reverse numbers...
    $height = $nwidth;
    $width = $nheight;    

}

Then just echo in the HTML the $width & $height variables as the width & height of the image.

Brett, Thanks for the reply. Unfortunately I know just enough php/html to hurt myself! If you would be so kind, a little more hand holding would be appreciated. Am I correct that I replace this:

<?php echo tep_image(DIR_WS_IMAGES . $product_info['products_image'], $product_info['products_name']); ?>

with your code? Also, assume the called image is 325 x 425 and I want the resulting image to be say, 225 x 325.
Thanks for your patience.

Okay, let's do this:
1.) Do you want each photo to have a specific width/height? (Yes | No)
2.) Do you want them to be a fraction of the current size? (Yes | No)

I'll go over both ways, but first, what does the function "tep_image()" do? Can you paste the code?

Thanks Brett. This file calls each image selected by a customer. Long story shortened, the product_info page rendered a thumbnail of the product with an option for the customer to 'click to enlarge' This seemed redundant so I set it up so the customer would see the full size image immediately. Unfortunately, as it now stands, the image displayed is way to big. Appox. 325 x 425. I need to reduce to say 200x300. At set size would be preffered as opposed to a %. Product_info is attached i hope!

AAAHHHH!!! No attachment!!!

Okay, so as you're attaching the file on your next post (or copying the file into [php] tags), which size do you want to constrain? The width or the height? I.e.

Do you want the images to be a specific width, but not necessarily the same height, or a specific height and the width can be variable. Or, would you rather specify the width & height?

Height & width. Some of the full size images vary slightly in size so i need to specify height & width so they all render the same size. I tried posting the file, but got the 'to many characters' error.

I can IM it to you?

copy the file, save it as (filename).phps
Upload it to your server,
post the link

I'll then give it a look.

The thing is, you're saying you want to show an image of specific size and you're going to be specifying the height & width. You can use CSS (instead of PHP) to define the height & width:

If that's what you want, just edit the file where you see the image tag. Otherwise, I'll take a look.

Thanks. This is more what I had in mind. I know this can be done simply with html. Just couldn't figure out where to put the code.

u can ignore one from Height or Width

and the browser will automatically resize for u and set the width according tho the image propotion.
