As USBill said, you can email photos from the iPad's native Photo app.
If you open the Photo app on your iPad and assuming you already have some photos loaded, you'll see the 'thumbnails' of those photos displayed. If you touch the little 'curly arrow' icon that appears at the top right hand side of the screen the title of the screen changes to 'Select Photos'.
Briefly touch the photo(s) that you want to email. They get a little 'tick' mark in their bottom right hand corner. If you change your mind about a photo, you can briefly touch it again to deselect it. You can send as many as you want in a single email.
Once you've ticked all the photos you want to email, touch the 'Email' button in the top left-hand side of the screen.
A 'New Message' email window will open and you can enter the 'To', 'cc', 'Subject' and 'Message' fields by briefly touching the message window in the appropriate location and typing in the necessary addresses or message.
Once you've completed all of this, touch the 'Send' button and you're done....
Have fun and enjoy your iPad.
