I understand the concerns, but often the inability to hot link or embed inline detracts from the readability of some posts and in some cases does not really prevent the undesired results. Most recent example of this would be Jack's post on the Quater Panel Guards http://www.defendersource.com/forum/...ad.php?t=30778
. Inline photos would have greatly improved the readability of this post in my opinion. Sure he could have made reference to things like "photo 1" or "photo 2", but this is also cumbersome and adds several additional steps for the user. There have to be something like 20 links to photos outside the control of the list with no guarantee that they will exist next week. As for slow load times vBulletin allows the user to select whether or not to show the images, or simply links.
Since the interweb is all about collaboration and information, my preference would be that we have greater ability to pull in other content and consume it in a blended fashion.
