Photobucket is one of the biggest and most popular image hosts we have today. They are hosting billions of images on their servers. Photobucket has recently released a new Upload extension for Firefox which makes it easy for the users to capture images from the internet.
Photobucket Firefox add-on adds an options for you to upload any image to your Photobucket account by simply right clicking on the picture and click 'Upload to Photobucket'
The process is simple and effective. Users will need to be logged in to their account during the first upload. This is not necessary again as long as user is logged into the site which usually means per session or even longer.
