Shot tips

ok some of my pics i get the so called compression. i don't know what is does but when i re size i use crop. also some of my pics are only 40KB how do i get the full potential?
in my more creative shots i could never get lightning shots. can anyone give me tips on how to capture lightning?
any weather themes and FS times that are very scenic would also help.
Thank you
