Why is WordPress blurring perfectly sharp and crisp images when uploaded via the media library or post/page insert image? It doesn't matter if I upload an image that has the same size as "large" predefined in WP settings/media or an image that is larger. The images get blurry - not in a small way either.
What I do is editing the images in Photoshop, resize to 800px wide and save as jpg.
I don't understand it. I have tested this back to WP version 2.8.6 and it is the same.
Does anyone know something about this or should I just accept this as a WordPress feature.
