Hello,

The product images are blurry except from the popup mode.
Why is this happening?



Thank you

Hi,

That comes from the webp images. In your case, it looks like the compression is too important.
The best for now is to add an entry with the namekey add_webp_images and the value 0 in the table hikashop_config via your phpmyadmin to deactivate the webp images.
With next version, you can change that back to 1 and instead add an entry webp_image_quality with a value between 0 and 100 (80 by default) to configure the quality of the webp images.

Hi,

I planned for this week. I'm still hopeful we can wrap up the release today but otherwise it will be at the beginning of next week.

Hi,

Then you must have made a mistake when added the entry to the hikashop_config. Please double check.

Make sure you don't have any extra space after the namekey or the value. I don't see why it wouldn't work for you while it does for everyone else we gave the same solution.

Hi,

That's a good point. But I don't think it should make any difference. You can try but I don't think it will help.
Note that HikaShop 4.2.0 has been released on Friday last week. So you can update and change the quality of the webp images with the namekey webp_image_quality and the value 100 in the hikashop_config table.
You'll have to delete the thumbnails folders after that so that the webp thumbnails can be regenerated with the quality you want.

Hi,

It's normal you don't have it. That's why I said that you need to add it and not to change it.
With most new options we add to HikaShop, we don't add the corresponding entry in hikashop_config during the installation, especially for options without a proper setting in the interface.

Hi,

I personnally don't see that the thumbnail of that image is particularily blury on your link.
The thumbnail is smaller and a bit compressed, so of course there is a bit less details to it. But it looks quite reasonnable to me.
You could change the code:
$quality = array(
'jpg' => 95,
'png' => 9
);
to:
$quality = array(
'jpg' => 100,
'png' => 9
);
in the file administrator/components/com_hikashop/helper/image.php in order to not have compression on the thumbnails generated by HikaShop. But I don't think a 5% compression quality change will do much.
If you really want to have better thumbnails, then you would need to use a better algorithm to resize the images. And that's not possible in PHP as there is only one. So you would have to resize the images into thumbnails yourself with an image where you would have a lot of control on that (like photoshop) and then replace the thumbnails in the /images/com_hikashop/upload/thumbnails/ folders of your website via FTP. This could be an harduous process, but I don't see any alternative if the thumbnails generated via PHP are not good enough for your needs.
