Are there regular installation images that include all the software available in Fedora?
Not by the Fedora Project. The Everything folder in the mirrors provides an installable repository but ISO images are not provided since they would be around 9 GB and not many mirrors would be willing to carry it. All installations of Fedora use the same central repository and all the packages are available via yum and front ends. There are retail vendors who provide a 11 CD set that contains all the software.
