Hi Stephanie, welcome to the wonderful world of seeds. Try different methods like indoor under lights, wintersowing, direct sowing, and sprouting in damp paper towels.
And yes, I added the above photos to the database. I remember how I searched for seed photos when I was new to seed saving. But if you allow blossoms to dry completely on the plants, you will be surprised at how quickly you learn to identify different seed types. The biggest hurdle for me to overcome was allowing the flower to remain on the plant long enough that the seeds were mature.
My favorite online source for seed photos is FRSA

If you open each plate in adobe you get big clear photos of seeds.
