Obviously this is something I'll need to address concretely in the future on my website, etc. I look at it this way.... if you get the OK from a colleague to use a design I did for them, fine, it's bought and paid for and you're sharing the wealth. However, if it's just being ripped off the internet or such, not cool. Taking credit for one of my designs is another thing entirely and is punishable by public ridicule (i.e. tar & feather or being called on it on this very forum).
ALSO, keep in mind, if the file that is stolen off the internet is sent to print or such, it WILL print like crap as it isn't a print quality file.
This all comes down to a matter of personal integrity which 99% of you definitley have in spades. I am very happy to offer my quality services at affordable rates and will continue to do so. A situation like the one in this thread is inevitable, as I've seen many similar instances during my years in the advertising business.
