Not sure I understand what you're asking, but I'll try to help
Which email programme are you using?
- If a web-based app. like gmail or hotmail, then I'd save your pictures to the desktop and add them to the email like any other files
- if a local app. like Mail or Entourage, save the files to the desktop again, select several at once by
Apple-clicking each file to be uploaded (or CMD-clicking as you'll hear it called) and drag them all at once into the compose window
That useful?
