Most everyone is going to get that red X image. To view the image, right click on the red X and select "Properties" from the drop down menu. Highlight the URL, right click and select "Copy". Close the Properties dialog.
Paste that into your browser address bar and press the Enter key. When done, use the back button to return to the forum. The image will appear in the post for this browser session. If you close your browser and reopen it and navigate back to this forum, it may well be a red X again, depending on your settings.
Many websites do not allow direct linking to images or content on their webpages to limit bandwidth usage. It is often better to provide a link to the website and webpage that the image resides on in post on the forums. It generates traffic for that site, gives a defacto source credit and avoids any misuse of terms of agreement or copyright infingement issues.
'Course, hosting the image on one's own webspace is always an option, but it is not playing fair unless the origin link is included along with the pic.

C'est magnifique, mais ce n'est pas la guerre.
