Amazon S3 Question

[pinion]

Does anyone have an Amazon S3 account they use? I played with it last night. Created a bucket and uploaded one picture to it (3MB). Then I made it public and got the address to it and opened it in my browser. This morning I look and I have 2 cents worth of charges. I don't think I can afford 2 cents for every picture I put on there. The charge is all on S3, not data transfer or anything else. Will each picture be like 2 cents a month?

PS. Happy Birthday JJ!
