Hi, I have modified the code to use ratios instead so that if you want to set a different max height to width you can ie. width = 650 and height = 550.

replace:

$image_info = getimagesize($full_file);
$original_height =  $image_info[1];
$original_width =  $image_info[0]; 

if ($original_height > $original_width) {
$largewidth = (600 / $original_height) * $original_width;
$largeheight = "600px";
} else {
$largeheight = (600 / $original_width) * $original_height;
$largewidth = "600px";
}

with:

$max_width = 650;
$max_height = 550;
$max_ratio = $max_width / $max_height; 

$image_info = getimagesize($full_file);
$original_height =  $image_info[1];
$original_width =  $image_info[0];
$original_ratio = $original_width / $original_height; 

// set some defaults
$largewidth = $original_width;
$largeheight = $original_height; 

if ($original_ratio > $max_ratio) {
if ($original_width > $max_width) {
$largewidth = $max_width;
$largeheight = round($max_width / $original_ratio);
}
} else if ($original_ratio < $max_ratio) {
if ($original_height > $max_height) {
$largewidth = round($max_height * $original_ratio);;
$largeheight = $max_height;
}
}

This is very nice hack, but i have have one problem. If i have smaler images(for examlpe 300px width), script forced resize image to 600px and my image loses quality. Is there some way to not resize if image is smaller than 600px?

Thanks

Thanks Jonnypixel,
I believe my next hack will be on this topics.
But I am not currently available to do this hack yet, maybe next week I am going to have more free time to do this hack. Because we are now in the time of wrapping up our first free exciting premium business template.
For my wild guess, and a bit of knowledge of VM, I believe you can look into this files.
1. administrator/components/com_virtuemart/classes/ps_product_category.php (this is where it control the admin side of it – I guess this is the place to hack. :-O wild guess only. havn't look deep in it yet.)
2. components/com_virtuemart/themes/default/templates/common/categoryChildlist.tpl.php (this is where the template call the category_thumb_image.

If you have found a solution to this, you can leave us a comment to share with the community.

That is awesome! thankyou so much. You dont know how many clients i get uploading like 12megapixel photos to their shop and then asking me why theres problems with the lightbox etc…
And all the photo resizing lessons i give them go over their head!

Can you please tell me if i can apply that script to the category area as well?

I would love to do the same for the Category image upload.
If you could tell me where that file is for ( image resizing / image categories ) i can have a go at inserting the code you have written.

Thankyou again for such a great modification to something thats really needed in VM
