I am presuming that your websites have copyright or the symbol with a date on each page? Or, you have some notice stating to seek permission from the owner to reproduce, etc.? If there's no notice or symbol, you have given a green light to copy your material. For some, I would recommend that you become familiar with "trademark" and you might need to register your logos, photos, etc. under that rather than "copyright". Every country has different rules for copyright and trademark and not everyone recognizes the rules the USA goes by.
