Looking for aerialphotos of Southwest coast of Florida. I used to be 
able to get them through Mapquest.

Hello,

You can use TerraServer, as Pink mentioned down below to get
topographical maps of S' Florida. For example, I put in co-ordinates 
of a town in SW Florida, and got a map that gave me maps raning from
very small to all of SW Florida. You can go by address as well if you
do not know the co-ordinates.

Example

Mapquest seems to not do their topographical maps anymore. I've heard
a few people say they are not their anymore.

If this answer requires further explanation, please request
clarification before rating it, and I'll be happy to look into this
further.
