E-mailing photos

Is there a way to increase the size of emails?  I frequently send photos and the 8 Mb size  restriction limits the email to 1 photo.  Is there a way to decrease size of  .jpg photo?  Often I must send several emails in order to include the photos I wish to send.  The 8 Mb restriction is really quite small.  Suggestion? 

Also, if I want to semd a video, I can't do that at all!  The iPhone can send video, why not verizon.net?.   Suggestion?
