Why can I send email but can not send email with attachments?

I have a new email and it not let me send an email with attachments, but i can send a standard email, why?

• Answer:

  Possible reasons and solutions #1: Go to the IE tools menu, click "internet options", click the advanced tab. Go to multimedia, mark "show pictures", click "ok". #2: Check your anti-virus and/or firewall security settings, they may be too strict. Go to where it says "disable web bugs", unmark it/ turn it off. (Web bugs are tiny images on a web page used for tracking purposes. But if you checked "disable web bugs", also no other images embedded in e-mail txt will show). #3: Your IE security settings may be set too high, thus not letting you access the web site which hosts the pic. To solve this in IE click "tools", click "internet options", go to security, mark "default level". #4: Are you using Windows XP and have the service pack 2 installed? Is Outlook Express your mail prog? After installing the SP2 a security option automatically gets turned on which "blocks images and other external content in HTML e-mail". To fix this go to tools, click "options", click "security" and unmark the "block images...", then click "okay".
