If you check the url of the image closely, you should see something like this...
<p><strong><img alt="traveler cal1" src="{{media url="http://some-direct-link-to-product.png"}}" />Some description of product</strong></p>
If you use a direct path which is copy-pasted, it could be identifying as a broken image processing the media_url path by the editor.
While it should be actually something like this <p><img alt="ohaus logo" src="{{media url="wysiwyg/some-link-to-product.png"}}" /><br /><br /></p>
To rectify this, in the WYSIWYG editor view client can right-click on the image (or skin image), pick "Insert/Edit image" option from menu. Give the full source in the text box "Image Url". You can upload and add pick the image in the same window here. Giving a direct url in that text box will eliminate the {{media url from the WYSIWYG source.
