Hi,
Sorry for the very late reply and thanks for the links, video, and login.
I was able to copy the test page shortcode to my localhost and I found that your shortcode is missing the image attachment ID:

This information is required, it looks like your WP All Import is missing it somehow. In my tests I found that the color section retained the URL to the image in the shortcode, but there is no attachment ID for the image, and this is what WordPress is looking for. Yet because this image doesn’t exist on my server, there is no correct attachment ID to use, thus the image won’t show.
If I then open the color section and click on the image thumbnail and upload that image to my localhost the shortcode is updated with the correct attachment ID and the image shows.

So I don’t know if your WP All Import is missing the attachment ID, or if during the import the actual attachment ID for the newly imported image is different and the error results in the ID being removed, or if your not importing the images and are relying on the URL to include the image, which would not work because you will also need the correct attachment ID.

Hi,

Glad to know that the solution that we provided above works.

To delete unused images, you could either do it manually by deleting the image from the Media > Library panel — this will also delete the thumbnails for that particular image — or use the following plugin.

Again it is very IMPORTANT that you have a site backup or a restore point before using the plugin.

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?

Best regards,
Ismael

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
