As far as the theme doesn’t create multiple images, this is the only image of that proportion. And I guess it’s the image from the header of the post?
Please have a look at the comparison in the attachment.
The picture on the left-hand side comes from the element, the one on the right-hand side is the one from the post, from the header.
These are the same picture, so in theory, they should be the same quality. But they aren’t. Please have a look at the BB date (upper side of the packaging) or the flavour name (under the ‘Warrior’ text in the centre).
I changed the size of the header photo to 2000 x 1000 px. It better fills the big picture in that element (I guess 1900 x 1000 will do the job in that matter perfectly). But still, it’s quality is poor.
Any ideas?
