Sorry to double post, but this is to address a way to help with images stretching the forum.
If you feel you'd rather not attach an image as suggested above by Mikeyj (still the best option really), you can use some post coding to keep the image within a 1024x768 display area. Yes, many people still have 4:3 aspect ratio monitors and for the sake of visibility stay at such a resolution.
If you resize the image before embedding, make the image 720 pixels wide or less. This allows for the left frame with the user info and avatar without invoking a horizontal scrollbar in a maximized browser window @ 1024x768. If you feel that too much detail is lost, you could provide a smaller thumbnail with a link to the full sized image. Most photo and image hosting services offer this capability. If you are hosting the image from a source that doesn't support thumbnails, and are not up to creating them manually, read on.
To embed an image resized to fit properly, use the following as your code template:
| Code: |
<img height="0" width="720" src="http://url.ext">
[url=http://url.ext]Click here for full size[/url] |
Replace the URL dummy link with the URL of your image.
For calculating the image height, here's a handy proportional size calculator:

As noted on the page, insert the current dimensions into the top fields then enter 720 as your width in 'New Width' then click the 'Resize!' button. If the new height yields a non-whole number (has decimal places), you can just round up or down yourself, or clear the field 'Number of decimal places' and hit the 'Resize!' button again.
