Let's say I want to show a pic of what I'm talking about how do I do this without breaking copyrights.
Lets say I get the image from the sony website for example. Is there a process where I can use the photo like . . . .this would be annoying e-mailing sony requesting that I use it . . . or do I provide a link back to the source or what.
Ask the copyright holder for permission. Most will give it if you simply ask them. They will tell you what legalese you need to use, and some may ask to see the site before it goes live so they can give an ok to it on the page.
Document what you did to try to get permission. If there is a question later, you can show them that you did diligent effort to try to get permission.
I have the official site of a well known product... and I want to include a screenshot. ...do I have to still ask for permission?
If you have the official site of... a well known product... then your official contract with the makers/manufactures/promoters should clearly state what rights you have relative to the usage of official images for marketing, and other, purposes...
