You probably uploaded a new image to replace an existing image, then decided to go back to the original, so you deleted the new image. The problem is that your browser is displaying the image in its cache, rather than the image on the server.

Your web browser caches images to speed up the loading of web pages. When it displays a new image, it stores that image locally (known as caching) along with the time the image was last modified on the server (known as the timestamp) and the URL of the image. Each time the browser redisplays the image, it asks the web server for the image's timestamp, and if the timestamp of the image stored on the web server is the same or older than the timestamp the browser has stored, the browser will redisplay the image it has stored in its cache.

When you replace image A with image B, the new image (B) will have the same URL as the image being replaced (A), even if it has a different name on your local filesystem. As always, the browser will store the timestamp for image B when it first displays this image. When you later replace image B with image A, the original image, the browser will ask the server for the timestamp for the image stored at the URL of the image. The server will return the timestamp for image A. When the browser checks to see the timestamp it has stored for the image at that URL, it sees that the timestamp for the image in its cache (image B) is newer than the timestamp for the image on the server (image A), so it will display the image with the most recent timestamp: the one from its cache (image B).

Most web browsers can be forced to reload the current webpage from the source files rather than the cache. This functionality is     usually bound to the key-combo Control-Shift-R. You can also try     clearing your browser's cache (the local storage of the images). This     is usually available in the preferences setting of your browser     where you can set other cache preferences such as the amount of disk space the browser uses for caching images, etc.

You may have entered an incorrect URL. Check to be sure the URL you are attempting to use is correct, then reenter the URL.

In Mozilla, Firefox and Netscape, you cannot select and move tables and images across the Edit Content tab's WYSIWYG editor with a mouse. Save your work, then click the Edit Source tab to reposition tables or images in the source.

Link targets (i.e., the HTML href) can be edited in WYSIWYG mode by highlighting the link text and clicking the 'link' button.
