Stop image downsizing?

put this to functions.php of your child-theme:

for Masonry Images

function avia_change_gallery_thumbnail_link($size){
  return "full";
}
add_filter('avf_avia_builder_masonry_lightbox_img_size', 'avia_change_gallery_thumbnail_link', 10, 1);

for gallery Images:

function change_lightbox_size() {
    return "full";
}
add_filter('avf_avia_builder_helper_lightbox_size','change_lightbox_size', 10);

per Enfold it is set to return “large”

and this here seems to be ruling the popup window size:

add_filter( 'avf_avia_builder_masonry_lightbox_img_size', 'enfold_customization_change_popup_size' );
function enfold_customization_change_popup_size( $size ) {
  return 'fullsize';
}

but the code for showing the original image is in thread on top

@raylay: first there are some imgSize Settings in WordPress itself (media.php) thumbnail, medium, large, full
You can set up those sizes (full is the uploaded image itself) on dashboard/settings/media

The other settings come from Enfold functions.php from line 136 (Register additional image thumbnail sizes)

$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']);

on avia-template builder / shortcodes / there are av-helper-masonry.php line 511 set image-size of lightbox to “large”
on gallery.php line 173 set image-size to “large”
