No pictures in email

When I receive a message in Comcast email that has embedded pictures I just show a blank box with an X in the corner. If I indicate I want html shown as an attachment the pictures show up as attachments. Has this got something to do with security or the manner in which I selected I want my emails displayed? They used to show up in the body of the email. Thanks

Hi,
Sorry you had to wait for a response to your question.
Usually problems of this nature are caused by either an overful temp files/cache, or security setting within your email client resticting images from being shown.
to resolve this
1 Perform a disc clean up (ATF Cleaner by Atribune) is excellent for this, available from here:

2 Amend security settings in your email client accessed usually via tools>Options>Security
