How do I send a folder of pictures on email?

Most email services have a size limitation for each individual email, so you're unlikely to be able to send all those pictures in a single email. I'd put them on Flicker or some other service. If you must send them by e-mail, just put two to four (depending upon size) in each email and send them that way.

folder cant be send by emails, u can use winrar or winzip to compress the folder either as zip or rar and can attach the compressed file in mail and send. else right click the folder and compres it to zip and send.
