Mrs B - another tip for you ...
When sharing pictures taken with the iPad camera, when you have put them in an email ready to send, you will probably see just below the "Send" button something like "Images: 2Mb"... if you tap the "Images" label you can choose whether to send the photo in Original size or have it shrunk down to Small, Medium or Large which means it will be sent quicker.
Quite often, Medium or Large is probably enough if you are just sending a quick snap or something that is "look once and delete". You can then keep the Original size if it is more of a "look closely at this thing" situation.
It is not as important when you (and the recipient) have landline broadband but if you (or they) are using a mobile connection, it can be really helpful.
It remembers your preference between pictures too.
EDIT : Oh, and if you want to send more pictures in an email at the same time, tap the Share icon (the square with the up arrow on it) and you will see a blue tick on the bottom right of the picture. You can then tap several other pictures and it will turn the blue tick on or off for those too. Then, when you tap the Mail icon, all the ticked pictures will be added to the one email ready for sending.
