Could you find me a picture of Mickey Mouse (in a costume) from disney
world, florida. He must be in full view (edges of picture must not cut
any part of him out, apart from maybe his lower legs / feet). Needs to
be good quality, good lighting (daylight), no text or watermarks
covering picture.

Hello tjkinsella-ga

Thank-you for your question.

I have located a number of full length images of Mickey Mouse for you
at Disney World, Florida.

I hope one of these images is sufficient for you (the first one was
particularly good I thought), if not it may help to know a bit more
about what you want the picture for and how you intend to use it.  If
you require any further assistance on this subject please do not
hesitate to ask for clarification.

Perfect, exactly what I wanted - better even.

Thank-you for the 5-star rating and tip!  They are both appreciated.
