I need to send several pics via email on my iPad(3) and have no idea how to do this.

Can anybody here please advise me how to achieve this? I need to avoid sending 33 emails with a single pic attachment to each!

There are many ways, but one directly from the mail app is;
Go into your email app and start an email
In the content of the message, hold down your finger until a popup appears, choose insert photo/video then choose your photo.
When photo is inserted hit return and continue adding as above.

Does the recipient have an iDevice? because "photo stream" really is the easiest way to send photos to other people.

Also, you can do this direct from the photos app. Open the photos app, choose an album - camera roll for example, then tap 'Edit' on the top-right. Tap the photos you want to email, a little blue tick will appear on chosen pics, tap again to deselect.

Then tap ’Share', top-left, then choose email.

This does work, however, if you try to do too many, the option to "send by mail" doesn't appear when you choose "share" so you have to limit how many photos you select before doing it this way, but yes, as long as it's not too many photos, this way works fine and I've used it many times.

Why not upload the pictures to an image hoster (imgur, flickr etc) and then just email the link.
