Unless your inclusion would qualify as "fair use" legally you cannot use any part of a copyrighted work without permission.
Despite the various "urban myths" (10%, 300 words, etc) floating around there is no preset amount that you can "borrow" without seeking the proper permission from the rights holder.
Yes. Editing an existing image (no matter how much/little) does not void the original creators copyright and without permission is still considered infringement.
Unfortunately, there is no clear answer to this in the law, and no apparent pattern to judgments.
Many questions about copyright boil down to "can I do this?"is this protected?who controls it?can we use it without a license?how much can we use without a license?who do we get a license from?how long will it last, how much will it cost, and is it worth it?
Copyright laws prevent individuals other than the creator of the work from copying, altering, distributing, or performing/displaying the work without permission. Much of the text of copyright laws, however, consists of limitations, defenses, and exceptions which allow specific unlicensed uses.
Unfortunately there are no clear guidelines on how much of a work can be used without a license.

Copyright protection is free and automatic, as soon as the work is fixed in a tangible medium.
Using copyright-free materials is much cheaper and easier than negotiating for a license with the copyright holder of a protected work.
Do you mean "violating a copyright"?A copyright is the right of the owner of a work to reproduce and publish (copy) that work. It is a legal claim to ownership. It asks for the law's protection of the work against theft, piracy, and plagiarism. It may be the author (originator) of the work or it may be the publisher who claims copyright protection.Every book that is published has a copyright notice, often indicated by a little c in a circle. Other creative works--films, musical compositions, software, and other kinds of "intellectual property"--have a statement of copyright on them somewhere if the owner wants to protect them.A copyright notice is kind of like a fence around your property. The fence may not do much to actually keep people out. But it does tell them where the boundaries are, and it tells them that the property owner (you) want to keep trespassers out. They can't climb your fence and walk on your land without knowing that they are trespassing.If someone takes possession of (steals) work that is owned by someone else and tries to reproduce it or sell it, that is a violation of copyright. That is illegal.You should tell someone important...
In most countries copyright is free, instantaneous and automatic.
There is no preset amount that you need to change. The law is absolute that you are not allowed to create derivatives of someone elses work without permission. No matter what alterations you make all you can own the copyright to is your changes, not the underlying material.
The biggest myth (or misunderstanding) about copyright is that it's designed to stifle creativity. In reality, the intent was to encourage creativity by making it financially viable to create for a living. Say you write a book that you want to publish and sell. If anyone else can copy it and sell it, you're not going to make as much money as you could have if you were the only source.Other myths include...Fair Use allows users to take 10% (or 30 seconds, or 60 seconds) of a work without permission. In reality, the "fair use" clause doesn't include any numbers or hard guidelines like that; in court, smaller excerpts have been found infringing, and much longer excerpts have sometimes been found not to be infringing.Creative Commons weakens copyright laws. In reality, Creative Commons functions as a broad license to enable usage of copyright-protected materials without additional paperwork. Creative Commons can't stand on its own--it needs copyright to make it work.Disney single-handedly caused the Copyright Term Extension Act in order to protect Mickey Mouse. In reality, Mickey Mouse is a registered trademark, and as such is protected in perpetuity as long as it's in use.
