How can I assemble all of my pictures into a gallery for email?

I want to email all of my pictures to my sister. I have seen galleries where
I just click a picture out of many on the gallery and it enlarges on my
screen…How do I do that. I have all my pictures in the same folder
(my pictures)…Can you tell me how to make a picture gallery for email?

u upload your pics to image host such as Photobucket.com.

your sister download the pics!
