I would think so.... I don't know. It would be better to not mess with it. If you're worried about it, try getting your free clipart from a different source such as http://www.universalclipart.com
No, but you may use the superscript "TM".
The circled "R" symbol in trademarks indicates that the trademark is registered with the United States Patent and Trademark Office (USPTO), providing legal protection and exclusive rights to the owner.
The registered trademark symbol, an R in a circle, indicates the preceding logo, slogan, etc. has been formally registered; the trademark symbol, a superscript TM, indicates the mark has not been formally registered.
The symbol capital R within a circle [®], or circled capital letter R, is the registered trademark symbol. This indicates that the product is registered with a national trademark office (ex: Registered, U.S. Patent and Trademark Office). If a trademark is not officially registered, then it will be marked with a superscript TM (in capitals).
TM is for a trademark and the R is for copyright. A copyright is used to protect art, literary works, and music. Gone with the Wind would be copyrighted. A trademark is a symbol, name, image, (etc.) that identifies a service or product. Like Pepsi has their logo, Playboy has the playboy bunny, etc.
Rossignol (Ski's etc.) use an R The "R" thademark means that the trademark is registered
The 'R' symbol goes after the trademark or logo.
Typing (r) should autocorrect to the registered trademark symbol.

Trademark because it has the "r" with the circle after the title, which means it is federally registered as a trademark. If it was copyrigh, it would have the "c" with the circle.
No; if it's registered, use the R, and if it's not, use the TM.
