Dear team,
I’ve uploaded “creative columns 5” onto my homepage. http://girisunyata.org/
Now I’m tweaking it and would like to change the image.
I see there’s only one image in my library it’s 1280 by 1810 px. However in content editing mode there’s a button (with an eye you can select click) that makes the same image exactly half the size.
So far I’ve been manually uploading 2 versions of images, 1 normal size, one double the size @2x using an external plugin.
But perhaps there’s another way within the Theme itself to have one image and then select the right settings?
Please advice on how this works and what it all means. 
Thanks a lot in advance.
Darryl
