Hack file administrator\components\com_k2\models\item.php which is responsible for thumbs creation from K2 side.

For example this will crop Small image to square where width and height is taken from width settings:

//Small image
$handle->image_resize = true;
//$handle->image_ratio_y = true;
$handle->image_convert = 'jpg';
$handle->jpeg_quality = $params->get('imagesQuality');
$handle->file_auto_rename = false;
$handle->file_overwrite = true;
$handle->file_new_name_body = $filename.'_S';
if (JRequest::getInt('itemImageS')) {
$imageWidth = JRequest::getInt('itemImageS');
} else {
$imageWidth = $params->get('itemImageS', '200');
}
$handle->image_x = $imageWidth;
$handle->image_y = $imageWidth;
$handle->image_ratio_crop = true;
$handle->Process($savepath);


as you can see 1line is commented out and 2 adeed...

See docs for class.upload.php at verot.net and play with available parameters.
Just add line(s) $handle->somethingofyourchoice
That library create that thums..

thanks very much,Luckas

Hi,Lukas..thanks for your reply.
Now,according to your way, it's perfect..then i want to add Height setting on K2 Parameters..it could be?

of course, I have used this way : $handle->image_y = $imageWidth*0.8;
but it's shot of perfection.

Yes, but still as a hack...
1. Add required value(s) to administrator\components\com_k2\config.xml
e.g.
param menu="hide" name="itemImageS_height" type="text" default="200" size="4" label="Item Small image height (in px)" description="" /

2. define new variables in mentioned file administrator\components\com_k2\models\item.php

//Small image
$handle->image_resize = true;
//$handle->image_ratio_y = true;
$handle->image_convert = 'jpg';
$handle->jpeg_quality = $params->get('imagesQuality');
$handle->file_auto_rename = false;
$handle->file_overwrite = true;
$handle->file_new_name_body = $filename.'_S';
if (JRequest::getInt('itemImageS')) {
$imageWidth = JRequest::getInt('itemImageS');
$imageHeight = JRequest::getInt('itemImageS_height');
} else {
$imageWidth = $params->get('itemImageS', '200');
$imageHeight = $params->get('itemImageS_height', '200');
}
$handle->image_x = $imageWidth;
$handle->image_y = $imageHeight;
$handle->image_ratio_crop = true;
$handle->Process($savepath);

I have hardcoded this only in models\item.php so i haven't it tested...

You Are Great !!!!
thank you very very much~:) i'm going to test it

ok, test it and let us know if it works..
By the way, this is direct way to custom/heavily hacked K2... Without possibility to simple update... :|
Agreed, that images tweaks are (atleast) for me really needed...

agree. This should be an option.
First "hardcoded" method definitely works. Here are some screenshots...

in fact, the result is beauty..



haha, lukas.
however,we have to modify category.xml as config.xml, so we can set width and height on category config
