Free Photo Hosting

Photobucket (http://www.photobucket.com)is the most popular site on the Internet for uploading, sharing, linking and finding photos, videos, and graphics. Your free Photobucket account can store thousands of photos and hours of video. Photobucket also offers free tools for making slide shows of photos, videos with music. You can share your photos and videos with friends by email, IM and mobile phone.

ImageShack (http://www.imageshack.us)is an intuitive and easy-to-use free media hosting service. It can be used to upload images, flash files, and movies, and share them with friends using any imaginable means.

SmugMug (http://www.smugmug.com)is a photo uploader, editor, and community portal all in one. It keeps 4 backup copies of each photo in 3 states. Retrieve them anytime. It offers unlimited storage. Your friends can see your photos without registering, and without spam. No Ads.

TheImageHosting (http://www.theimagehosting.com/)allows to upload multiple pictures at one time, link your photos in web sites, email, blogs, register an account to manage your files, create online photo galleries for free, and more.

ImageVenue (http://imagevenue.com/)is a free image hosting solution. It is designed for you to share digital pictures with friends, post images on message and bulletin boards and blogs. You can also hot link images from your personal website or eBay auctions.

May I also add http://allyoucanupload.webshots.com/. I use this all the time. Very vast upload speed, you can upload almost any amount of images at once, super easy to use. You can upload them in any size you wish, as well. You can also create a free account if you wish, and keep all your files in folders.

And if you keep cookies, you can view your past uploaded images, even if you don't have an account. Kinda like on imageshack.

Flickr is another good site, you can only have 3 sets with a free account, but you can delete sets to make a new one.

what are the pros and cons of the primary hosts?
