See Verify an email account’s outgoing server. Make sure the outgoing (SMTP) mail server is specified as directed by the provider of your email account. This usually isn't a problem but sometimes people disable the downloading of external or internet images in their email app settings and this can stop the pictures from loading properly.

Sometimes an email app will require the user to manually initiate the download of the images you've sent them before they can see them. Only send an email after all of the files have uploaded completely. Most email apps and websites will feature a visible progress bar near where you attach files that can show you their upload status. If you hit the Send button shortly after attaching your photos, it's possible that the files didn't finish uploading to the email service provider in time.
