Photobucket is very easy.

Way less commercial than this forum- and don't think you'll be getting any viruses via photobucket.

I'm a huge fan of picasaweb. That's a branch of Google. Signing up gets you a free basic photo editing / management tool that links right in to the web pages. There's very, very little advertising and it's really easy to use.

what about shutterfly?

I have shutterfly and love it. It is very user friendly and free. They even give you free prints when you sign up and periodically throughout your membership (for lack of a better term). So far, I have not experienced any virus or spam due to shutterfly.

I'm another fan of Shutterfly - great pics, did very fun calendars for family last Christmas - huge hit. They are currently updating some software that will supposedly make uploading/downloading a little faster. Very user-friendly, no worry about viruses.

I really like Picasa. Their photo editing software is pretty good and very easy to use. I downloaded it after I bought a new camera and read good reviews about the desktop part of the utility. Uploading your pictures to the web is VERY user friendly. Picasa (like photobucket) also has links you can use to copy and paste into your posts.

I ended up using Picasa for forum posts rather than my other paid account (Pbase)
