user2120: I have a stop motion animation of about 35 seconds in duration (~150 frames). The resolution is quite large at around 900px x 450px.
What is the best format to play this looping on my website? I think my options are either .gif, standard .swf, or convert it into a movie .swf.
What is the recommended approach to this? I want the images to have a high fidelity and I was hoping to not use flash due to Apple incompatibility.

user1890: Likely the best solution is take your frames into a video editor, set the still pix time to about 0.23 sec for each shot as you indicated you wanted to show 150 frames in 35 seconds.
35 / 150 = 0.233333333
Set your project properties to 720p, (720 x 1280 progressive)
As you have 2:1 aspect ratio there will be some letter boxing.
Or a better match maybe to use iFrame format:
960 horizontal by 540 vertical pixels assuming you are using iMovie of FCP.
Assuming iMovie, render to .mov and follow these instructions to make it a .swf movie:
