Hi,

Thank you for following up.

Did you regenerate the images after adjusting the thumbnail size? You could also upload the images again manually, but regenerating the images is probably much faster and easier. The thumbnail regeneration option is in the same panel as the thumbnail adjustment options. But if you cannot find it in the same panel, try to install this plugin instead.

Hi,

We just realized that most of the thumbnails generated by the theme are scaled instead of cropped, so the size of those thumbnails might differ depending on the size of the original images. Fortunately, there is a thumbnail called “Shop Catalog” with the crop parameter enabled, so we selected that thumbnail from the Styling > Appearance > Preview Image Size settings to keep the height of the images the same.

FYI, the login info above is incorrect.

Hey!

Alright. The large thumbnail is set as the default size for the lightbox script, and currently the width is set to 1030px. You have to adjust the width and height of the large thumbnail in the Settings > Media panel, and as suggested above, you have to regenerate the thumbnails or upload the images again afterwards.

Now if you want to decrease the file size of the generated thumbnails or images, please refer to our suggestions above. Just use the filter in the functions.php file, refresh the page and once again, regenerate the thumbnails or upload them again.

However, if you want to use a different thumbnail size other than the default large thumbnail, try to use the provided filter in the previous thread.

This should set the lightbox thumbnail size to full instead of large.

Hi,

I actually edited each element on your page and copied image link from thumbnails, deleted -80×80 part to get fullsized image instead of thumbnails, downloaded them on my computer and re-uploaded them in element :)

Hey!

These file-size is best for the file – but we recognize that a lot of the calculated are much bigger than the original file.

Since the previous filters are not working in the child theme, it is possible that the quality is still set to 100, or that the compression level was not decreased during the time the images are uploaded, and thus the size of the generated thumbnails are bigger compare to the original image. If am not mistaken, you are already aware of this.

Hi,

The image used in the lightbox container is actually a thumbnail. Please try to add this snippet in the functions.php file to adjust the compression quality of the uploaded images including the thumbnail used in the lightbox container. And after adding the code, refresh the page, then upload the images again or regenerate the thumbnails.

 add_filter("avf_jpeg_quality", "avf_set_quality_mod", 9999, 1);
 add_filter("avf_wp_editor_set_quality", "avf_set_quality_mod", 9999, 1);

 function avf_set_quality_mod($quality) {
	$quality = 80;
	return $quality;
 }

The theme sets the default quality to 100.

Best regards,
Ismael

Hi,

Could you also provide the FTP details? We would like to check if the thumbnails actually exists in the uploads folder. Right now, the grid or the Blog Posts element falls back to the original image instead of displaying the selected thumbnail.

We actually deactivated the Smush plugin. Did you configure it before?

Hi,

Thank you for the update.

I try to manually remove them using the following your snippet in the functions.php

Adding the snippet in the functions.php file will only deregister the thumbnail sizes but it will not remove those that are already generated. To remove the existing thumbnails, you have to regenerate the images using the plugin (Regenerate Thumbnails) that we suggested above. This process might take a while depending on the number of images uploaded in the site, and since the site contains many, expect it to take some time.

IMPORTANT: Please do not forget to create a backup or a restore point before proceeding with the thumbnail regeneration.

Best regards,
Ismael

Hi,

Glad to know that it is working. :)

You could use the following plugin to adjust the default size of the thumbnails. The name of the thumbnail size used for the related entries is “square”.

// https://wordpress.org/plugins/simple-image-sizes/

The size can be changed in the Settings > Media panel and you have to regenerate or upload the images again afterwards.

Hi,

Thank you for the update.

Do you actually check the generated thumbnails instead of the full size or the original version of the image? Please note that the jpeg_quality will only affect the generated thumbnails, but not the original source of those thumbnails.

This filter works properly on our end.

 add_filter("avf_jpeg_quality", "avf_set_quality_mod", 9999, 1);
 add_filter("avf_wp_editor_set_quality", "avf_set_quality_mod", 9999, 1);

 function avf_set_quality_mod($quality) {
	$quality = 100;
	return $quality;
 }

Please check the screenshot below.

quality: https://imgur.com/zcVAIdU
file size: https://imgur.com/PDFZp1B

You could clearly see the quality and file size difference when the default_jpeg_quality is set to 10 version 100. Selected size is Fullscreen Sections/Sliders.

Ismael
