Hi Chaiwat,

I've just implemented a config setting to allow external images. After the next release of mojoPortal you can add:

<add key="Forum:AllowExternalImages" value="true"/>

to your user.config file.

However, allowing external images to be posted in the forums can potentially be a security risk. Also if you use SSL on your site (which everyone should these days), external images can cause browser warnings about the page containing insecure content.

The Blog module is designed for trusted users that is why it allows any content, you should not let strangers edit the blog because it allows even javascript which can be used for good purposes but also for malicious purposes. The Forums were designed for untrusted users that is why we limit what it can do.

This change is in the source code repository now.

Hope that helps,

Joe
