Photos need to be posted on to gmail email

Hi I have some photos and images of people and film posters. I need these to appear on email when I send a message, but not as attachments. So when the recipient opens the email they see the images straight away. ( I am using gmail ) Images need to be the same size so you might have to 'play around' with the size of images I send you. Am having a few problems uploading images to send you so would prefer if I could send them as attachments to your email address. Job needs to be completed by midday Monday 22 July.
