Images can be inserted as Flash objects

[James Cunningham]

Steps to reproduce the defect:

1. Open the Ajax sample.

2. Open the flash dialog.

3. Insert the following image URL into the URL field ​http://a.cksource.com/e/1/img/logo-ckeditor-h100.png & click OK. See that a flash placeholder is inserted into the editor.

4. Remove the editor.

Result: The image is displayed although it is a flash object.

Flash place holder is displayed in editor only.

When you remove the editor the flash content is saved in the document. It may look like an image but it's an image inside flash object what can be easily checked with Firebug.

I believe that the ticket is more about being able to pass an URL to any file in the Flash dialog (text files, images etc.) and that no kind of URL validation is performed.

In any case I guess it can be left as invalid. Some users may want to paste an URL that points to a .php file that serves some random flash object, so restricting the URL field only to flash extensions might be too strict.

Since it's possible to specify custom validation rules using JavaScript API, I'd leave it as it is now.

Eventually, the other possible option would be to ask user for a confirmation whether the URL to a file is really valid (just like when pressing Cancel button), if the extension does not match some pattern.
