In Windows 7, there is a different way to e-mail photos, which is very useful.
First, find and select the photo(s) you want to send. Looking along the options at the top of the folder or library window, chose “E-mail”. A new window will open, allowing you to choose different picture sizes – medium is usually OK, but if you are sending a lot of photos, you may want to choose small; click Attach. Now your mail window opens, allowing you to fill out the address, subject, and put some text in the message. Now click Send. Job done.
The advantage of this method is being able to choose the picture size – effectively cutting down on the size of the e-mail you are going to send.
You can send photos by attaching them to an e-mail in the normal way (create the e-mail first, and then click on Attach File (the paper clip symbol) , browse to the photo, select it, click Insert). This method sends the photo at its original size – which may be very big! And if you want to send several photos, you may find that the e-mail won’t go, because you have exceeded your allowed e-mail size.
