When emailing photographs you should always bear in mind that the file size of photos taken with most modern cameras is very large, and that sending multiple photos could cause issues for the recipient - especially if they have a slow internet connection, as it will often mean they will struggle to download the email which will in turn give them problems accessing any other emails
So make sure you either resize the images using your chosen photo editing software before sending, or if using Microsoft Outlook or eM Client use the process below which will do this for you automatically (N.B. this method will not work if using a web based email service)
1) Firstly select the photos that you wish to email (N.B. to select more than one at a time hold down the Ctrl key on your keyboard as you click on them)

2) Next right mouse click on the chosen photos and select Send to > Mail recipient or Show more options > Send to > Mail recipient for Windows 11

3) You will then see the following prompt - where you can choose what size to send your photos and it will show you the resulting file size - try not to send more than 2mb per email - that way you can make sure your recipient won't have any problems receiving it

4) Outlook / eM Client: The photos will then be added to your email, ready for you to enter recipient, subject and a message in the usual way - when ready you can click Send
