I have an image site which based on Wordpress. There are different resolutions below the picture in single post. For example:
1024*768 - 1200*900 - 800*600
When I click on one of these resolutions the image downloading directly to pc. Also creating these resolutions in wp-content/uploads folder. I want to remove one of these resolutions and add a custom dimension for uploads folder. How to make this please? Thanks.
