Funny pic, although those are the wrong type of pumpkins to make a pie from.
You want to use pumpkins like these (cheese pumpkins):

I make pumpkin pie from real pumpkins every year here is the recipe:
-Cut pumpkin up into wedges. Steam in pot until tender and flesh can be easily scraped from the skin.
-Take scraped pumpkin and blend until you have a smooth puree. Blot puree with coffee filters to remove as much water as possible
-Mix 3/4 C sugar (could use 1/2 C if you like less sweet pumpkin pie which i usually do), 1tsp cinnamon, 1/2 tsp ginger, 1/4 tsp nutmeg, 1/2 tsp salt together
-Take 2 C pumpkin puree and blend with 2 eggs, putting in eggs 1 at a time. Add in sugar mixture
-Add in 1 C heavy cream or 1/2 and 1/2.
Add mix to pie crust. Cook in preheated over at 425 for 15 minutes. Reduce temp to 350 and cook for 40-50 minutes until a knife inserted into center of pie comes out cleanly.
Very easy. You can add cloves, but I usually never do because I don't like them. All ingredients are real, nothing comes from a can. Libby's pumpkin pretty much dominated all pumpkin pies and they are owned by the same company that makes evaporated milk which is why it is semi-difficult to find a recipe that does NOT use nasty things like evaporated milk.
here's how my pie turned out, i made the crust from scratch too:
