Might as well skip the appetizers and start with the main course. Florida's digital archives are housed at Florida Memory.
This is an extensive online collection which describes itself as "...a selection of historical records that illustrate significant moments in Florida history, educational resources for students of all ages and archival collections for historical research..."
There's a lot here, beginning with a sizable Photography Collection of more than 160,000 photos and images. You can search the entire collection, or browse the photos by theme...the pictures are arranged in a series of Photo Exhibits
The Florida Online Classroom collection is a series of Educational Units that include:
There is also a Florida Film and Video Clips unit, that includes quite a number of diverse films having to do, in one way or another, with Florida. There's a page of additional films including The Adventures of X-14, about an alien landing in St. Petersburg Beach.
A collection of the Highlights of Florida History provides the archives' images of historically significant documents, by historical period:
On the page of Collections, Databases, Finding Aids, and Indexes there is a terrific set of resources, as listed below. A lot of the materials are useful for family history research, and I've linked to these:
By the way, there's a separate homepage for the Florida State Archives and a full-fledged archives search tool for their offline holdings.
I also want to mention the University of Florida Digital Collections, which has several Florida-specific collections, including newspapers, law, oral histories, and photographs.
