There are quite a number of issues in your question, I will answer several based upon the information you provided:
I am not sure what "....." may represent. If this is a name or region, you are not necessarily afforded much protection.
WA state TM registration is a $65 filing fee and the federal TM registration is $275-$325/class filing fee. It is strongly advised to have an attorney handle a federal trademark registration.
WA registration is not examined, outside of doing a "knockout"...
There isn't an easy answer with the facts that your provided. A common law or state trademark wouldn't [necessarily] extend into Washington. However, a federally registered trademark would create an issue for you if, and only if, your mark is likely to cause consumer confusion with the trademark holder. A trademark attorney could evaluate this and provide an solid opinion without spending a great deal of time or money.
Under some circumstances, you are permitted to use a trademark in a domain name to refer to that trademark's good. This is called fair use.
The 9th circuit (which includes Washington State) looks at the following three factors when determining a nominative fair use defense: 1)the product was readily identifiable without the use of the mark, 2) the mark was used more than necessary, or 3) a one claiming fair use falsely suggested a sponsorship or endorsement by the trademark holder.
If you are the photographer, you own the copyright on the photo. You can send a DMCA takedown request to the ISP of the website. This is the cheapest and easiest option.
You (or a lawyer) can also send a cease and desist letter directly to the website owner. If the copyright is timely registered with the Library of Congress (within 90 days of publishing), you can potentially receive statutory damages and legal fees in a copyright infringement case in federal court.
Finally, if there is a...
The other attorneys have properly mentioned copyright and personality rights (rights of publicity). In Washington, personality rights are codified in RCW 63.60. Fair use is also an area that might factor in, but it does not appear to be relevant here.
However, this should be a moot point because the artist release and/or license agreement often covers these aspects. Also, check with the agreement with the A&R Rep. If this isn't already part of the agreement, then you should consider working...
In somes cases, use of a copyrighted image without permission is protected under fair use.
Fair Use factors:
1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
2)the nature of the copyrighted work;
3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
4) the effect of the use upon the potential market for or value of the copyrighted work.
When using a...
It is probably not acceptable to do this. This would be the "copying" of copyright law. Furthermore, I do recall that the copyright on Mickey Mouse has not yet expired.
Is there an exception? Fair use might provide an exception, but it is not likely based upon the facts that you have provided. Also, I would not be surprised if Mickey Mouse is covered under trademark law as well. Fair use for trademarks, while available, is a higher bar than copyright fair use. If you would like to pursue this...
Technically, you may be guilty of copyright infringement. If the work has been timely registered with the US Copyright Office, you could be liable for statutory damages which can be as high as $150,000 per infringement plus attorney's fees.
Personally, I haven't seen damages exceed $30,000 on a trial for this type of infringement and damages can be substantially lower even for willful infringement.
If your use is deemed non-willful, damages can be as low as $200.
In these types of...
