Main page "Image Show GK4" bad image quality

palosutca

Hi,
It seems when I put an article (K2 item) into the slideshow it does not use the XL or L size cached K2 images but scales up the item's M sized (default 800px wide) image. Well if I increase the default "M" width to a larger size... it seems to be a bad idea as it will slow down the site using always the large images.
Also there is a setting at the module interface where looks like that I can do do something with the image size but it is initially set to 640x320px what is lower than the 'M' sized (800px wide) item image so I do not believe in it.

Should I find and change the modul's php or xml file to avoid the pixelated and upscaled images on screens with larger resolution than the SVGA? 😉

Of course I would have to know how to create a file override for the GK "system" but here is the magic:
Just change "_M.jpg" to "_XL.jpg"

modules\mod_image_show_gk4\styles\gk_photo\view.php

$thumb = 'media/k2/items/cache/'.md5("Image".$k2Item['id']).'_XL.jpg';
              		$hasThumb = file_exists(JPATH_ROOT . '/' . $thumb);
              		if (!$this->config['image_show_data'][$i]->image && $hasThumb) {
              			$path = JUri::root().'media/k2/items/cache/'.md5("Image".$k2Item['id']).'_XL.jpg';

palosutca Hi. That's a correct solution. This slider style was prepared for a template where a smaller area were occupied. So it was better to use Medium sized images due to page load speed.
