Notes:

To copy more image links you can go 'Previous' and 'Next' on the image page on photobucket to go through your pictures.

You can also set up albums to organise your pictures, but do this before posting on here as your links may change.

You can view all pictures at once if you browse through your albums, and hovering over them also offers an IMG code to copy.

There are many more features, such as using it to generate multiple IMG code at once among others. Have a play around with it and you'll soon get used to it.

Other services are available, but photobucket is a good free one to use
