Flickr
Free account: 20MB upload per month, only 200 most recent photos visible, only 3 galleries
Paid account: 2GB upload a month, no storage limit, no gallery limit, no bandwidth limit - $24.95 US / year
Pros:

• Very big community. If my goal is sharing, there are a lot of people, including people I know, you can make friend lists, there are groups and forums, etc.. Very social
• Very feature rich, lots of options for organizing, tagging, and distributing photos, some very sexy interfaces
• Paid account has by far the widest limits
• Widest support from other online sources, or 3rd party programs which tie into the flickr API

Cons:

• I find the site performance lags a bit, browsing pages on flickr is not as fast as I would like.
• I find some aspects of the UI counter-intuitive. While some interfaces are super sexy and smooth, other pages feel clumsy and awkward.
• worst free account restriction by limiting hosting to most recent 200 pictures

PicasaWeb
Free account: 250 MB storage, all photos available, no gallery limit
Paid account: 6 GB total storage - $25 US / year
Site is still in beta, so features may expand
Pros:

• Most intuitive and easy to use interface
• Best slideshow interface
• Excellent site performance
• Would take me a looooong time to use up the free account space, possibly over 3000 pictures

Cons:

• No tagging - unfortunate limitation…and one I have to think they will fix eventually
• Little support from 3rd party options to tie into the api, may change with time.
• Quite a bit less built in community.

Livejournal
Free account: no photohosting
Paid LJ account: 2 GB storage <– I am already paying tor LJ, so this level is already available to me
Extra storage: 10 GB storage - variable rates, but about $25 US / year
Pros:

• Already paying for the basic level, so starts with the best available storage to me without paying anything extra (compare to the free offerings of the other sites), though I can’t imagine how long it would take me to fill it up.
• I can tie visibility restrictions into my existing friends list.

Cons:

• Interface is very basic, clumsy to use, very little 3rd party tie in….basically the service, as a photo hosting service, is still very  primitive. They provide the space, but the experience is very limited.
• No slideshow option I know of.

Private hosting
Not much to say here….I am not sure what the bandwidth limitations will be, I would need to get some software to organize it, etc… yadda yadda. But it *is* an option
