How can you tell from a picture if.....

[Eternal]

The question is how can you tell from just a cover picture if something is a first print or a second print. I know I could just email the person and ask but that takes forever. The one i'm wondering about is Star Wars (77) #6.....in the guide there is a 6A and 6B, is there anyway to tell the difference by the cover picture. Any help would be great. Thank you.

It says reprint along the bindery in the box in the upper left corner. Or I think if there's a diamond, it's reprint too.
