If your using Outlook Express, this was a security addition with SP2
If you want to change it...
When Outlook Express is open
> click Tools
> click Options
> click Security
> Under Download Images > Untick > Block Images and other external content in HTML content.
Close and re-open Outlook Express. If you have pics in your email, you should now be able to view them.
As far as blocked files goes...It is the new security settings in SP2
The new security settings in SP2 only applies to files sent from someone else's
computer. Sending yourself files can't harm you. It is when potentially harmfull files (Microsoft's words, not mine), are sent to a different computer that is set up with this default SP2 security setting, the recieving computer will block these files.
Frustrating? Yes. Security can be frustrating...been to an airport latley?
Is it overkill..IMO...yes, I believe SP2 went overboard in it's security. But a few adjustments in your security settings will allow you to change it, and then we can recieve these safe files from Alec. But then again, I think the Patriot Act went ..ahh nevermind, that's another story.
However, if you make these changes in your security settings, this will mean that you will have to use your own good discression when opening any file.
Therefore, it may be better if you just leave the security settings as they are, and if you know the person who sent the file, you just need to Right Click the file and check unblock...easy enough.

Configuring Blocked File Extensions
Microsoft Windows SharePoint Services provides the ability to restrict certain kinds of files from being uploaded or retrieved, based on the file extension. For example, a file with the .exe file extension could potentially contain code that runs on client computers when it is downloaded. Because it has the .exe file extension, the file can be run on demand when it is downloaded. If files with the .exe file extension are blocked, users can neither upload nor download a file with the .exe extension, and potentially dangerous content in the .exe file cannot be downloaded. This feature does not prevent all exploits based on file types, nor is it designed to do so.
By default, several standard file extensions are blocked, including any file extensions that are treated as executable files by Windows Explorer.
Add or remove a file type from the list of blocked file extensions
Click Start, point to All Programs, point to Administrative Tools, and then click SharePoint Central Administration.
On the SharePoint Central Administration page, under Security Configuration, click Manage blocked file types.
On the Manage List of Blocked File Types page, perform one of the following actions:
• To add a file type, click in the list and type the extension.
• To delete a file type, delete the file extension from the list.
(Or unblock the folder as I described above.

Sometimes too much security is not
a good thing.
