Blog post images

What is the best size for uploading featured images for the Game theme.

I am concerned about the amount of space the images are taking up on the blogs. Also the kind of images im uploading - they often have text in, results in blurry zoom effect.

However all in all i like the zoom effect - and would like to retain it.

I am using just the sidebar and image window width seems to be 744.

Please advise before I try to optimize.

I have already tried to add featured images but find it extremely frustrating to get it right.

Hello,

1280 x 720 are default size of featured images in teh Game theme.
Could you please provide me with a URL to your website, either here or via PM (click the “Private Message” text underneath my avatar) so that I may analyze it?
