can someone suggest a good photo uploading site?

OK i'm looking for something fairly specific here, so these are the criteria:

1. I will be uploading a decent number of photos each month and need something that allows bulk uploads (5 at a time doesn't count, at least 100 at a time, or a whole folder at a time)

2. The photos can be resized, that will not be a problem.

3. There is preferably no limit on the number of pics, or storage size cap. If that is not possible, then at least a really high limit.

4. A small subscription fee is OK, maybe $20-30 a year, but preferably free.

Can someone suggest a good service/website given these criteria?

Thanks in advance for anwers
