Hi,

Thanks for the update. I think it happens because the theme or WP returns the thumbnails with the highest quality. Please try this filter in the functions.php file.

add_action('after_setup_theme', function() {
    function av_return_75(){ return 75; }
    add_filter('jpeg_quality', 'av_return_75');
    add_filter('wp_editor_set_quality', 'av_return_75');
});

It will override the theme’s “av_return_100” function.

if( ! function_exists( 'av_return_100' ) )
{
	/**
	* Sets the default image to 100% quality for more beautiful images when used in conjunction with img optimization plugins
	*
	* @since 4.3
	* @added_by Kriesi
	*/
	function av_return_100(){ return 100; }
	add_filter('jpeg_quality', 'av_return_100');
	add_filter('wp_editor_set_quality', 'av_return_100');
}

IMPORTANT: You have to regenerate the thumbnails.

Hi,
Sorry, I’m not sure I follow.
I understand that you have 10k photos to upload, so all the extra files is no good.
Then I think you are saying you only need two sizes for each image?
If this is true, you can remove some of the sizes in the functions.php look for:

/*
 * Register additional image thumbnail sizes
 * Those thumbnails are generated on image upload!
 *
 * If the size of an array was changed after an image was uploaded you either need to re-upload the image
 * or use the thumbnail regeneration plugin: http://wordpress.org/extend/plugins/regenerate-thumbnails/
 */

$avia_config['imgSize']['widget'] 			 	= array('width'=>36,  'height'=>36);						// small preview pics eg sidebar news

);



avia_backend_add_thumbnail_size($avia_config);

and remove the ones you don’t want, be sure to save a copy of the original file should you make an error.
Or you can use the plugin above and set the size to zero for the images you don’t want, this might be the best option.
After you remove your sizes please use this plugin: Regenerate Thumbnails
As you remove each size check your site to ensure the size you removed is not used elsewhere.
Best regards,

Hi,

We are very sorry for the late response.

Please use this css code to remove the copyright container on a magazine element.

.av-magazine-thumbnail .avia-copyright {
    display: none;
}

Thank you for using Enfold.

Best regards,
Ismael

Hi,

Also, I have noticed that pictures which are resized by Enfold/WP are greater in the size than their original files, even though the modified picture is smaller, e.g.

The thumbnail is actually smaller than the source or the original image.

vs the bigger original picture

Hi,

You can create your own custom thumbnail or use the ones generated by the theme.

$avia_config['imgSize']['widget'] 			 	= array('width'=>36,  'height'=>36);						// small preview pics eg sidebar news
$avia_config['imgSize']['square'] 		 	    = array('width'=>180, 'height'=>180);		                 // small image for blogs
$avia_config['imgSize']['featured'] 		 	= array('width'=>1500, 'height'=>430 );						// images for fullsize pages and fullsize slider
$avia_config['imgSize']['featured_large'] 		= array('width'=>1500, 'height'=>630 );						// images for fullsize pages and fullsize slider
$avia_config['imgSize']['extra_large'] 		 	= array('width'=>1500, 'height'=>1500 , 'crop' => false);	// images for fullscrren slider
$avia_config['imgSize']['portfolio'] 		 	= array('width'=>495, 'height'=>400 );						// images for portfolio entries (2,3 column)
$avia_config['imgSize']['portfolio_small'] 		= array('width'=>260, 'height'=>185 );						// images for portfolio 4 columns
$avia_config['imgSize']['gallery'] 		 		= array('width'=>845, 'height'=>684 );						// images for portfolio entries (2,3 column)
$avia_config['imgSize']['magazine'] 		 	= array('width'=>710, 'height'=>375 );						// images for magazines
$avia_config['imgSize']['masonry'] 		 		= array('width'=>705, 'height'=>705 , 'crop' => false);		// images for fullscreen masonry
$avia_config['imgSize']['entry_with_sidebar'] 	= array('width'=>845, 'height'=>321);		            	// big images for blog and page entries
$avia_config['imgSize']['entry_without_sidebar']= array('width'=>1210, 'height'=>423 );						// images for fullsize pages and fullsize slider
$avia_config['imgSize'] = apply_filters('avf_modify_thumb_size', $avia_config['imgSize']);

Again, you can use the suggested plugin above to adjust the size of the existing thumbnails or to create your own. :)

Hey nychng,
When I go to the “wrong” site and click on the main product image, it opens in lightbox, same as when I click on the thumbnails below. This is the default behavior.
Please see this demo
But when I go to the “correct” site and click on the main product image, it zooms in, I believe this is the action of a plugin.

Best regards,
Mike
