Why does the picture of the blog so blurry and is there any method?

Hi, Thanks for reading.

I'm curious why the picture of the blog is so blurry.

I double-checked that the resolution of the picture is okay... I'm convinced that picture just had bad resolution.

Is there any method to fix this?

Hello @KimKimKimKim 

Here we checking that your image is 480 px but where the image is being shown there is a requirement for an image size of 800px so please upload the images of the size you require so that the image will not appear blurred.
