How can I invoice an international buyer who hasn't paid yet?

I use the same camera to take pictures. Why can I use some of them but some say corrupted. How do I fix this?

I take pictures from the same camera. Some photos are fine, while the others say corrupted when I try to upload. Why is this and how do I fix it?

This is confusing to me. I read the two articles, can’t print them out, but I don’t know what do do. Please help.

A buyer just purchase 3 individual items and I would like to combine all of them with one shipping cost. How do I do it?
