I’m currently setting up the site in my localhost. It is actually the image which is cropped to height 500px.
Can you share a few of those images by uploading them to imgur.com
I’ll try it on my local installation.
The image has been uploaded to the said URL:
View post on imgur.com
Is it the thumbnail or the slider?
I added this image as a “featured image” to a post and it was cropped to 300×167.
If you mean the slider, the solution is to edit the class-fire-init.php file in /wp-content/themes/customizr/inc. Find the following code
add_image_size( 'slider-full' , $width = 99999 , $height = 500, $crop = true);
add_image_size( 'slider' , $width = 1170, $height = 500, $crop = true);
Change the $height
value to your preference.
After this you have to delete the existing slider images from the Media panel and upload them again for the changes to take effect.
