Thread:Extension talk:WYSIWYG/Image copy/paste from word and clipboard doesnt work/reply

Have you checked this thread: 404_page_not_found

If you look at this table Version_of_source_bundles you can see that there are quite many different "versions" out in the world. It may be helpfull if you could tell what version you are using (version of MW, php, wysiwyg.php, installation source bundle used, version of browser...)

In my installation of MW 1.22 (#6 of Version_of_source_bundles) it works in same way as in yours if I try copy-paste for image. Canceling edit of page works without problems, (I have made modification 404_page_not_found).

The only way I can add images is to first create "image link" using Picture -button, if you already have image ready in MW, you can select image from the list and save the page. If image is new, then finish the image link dialog and save the page. After that you can see upload link on saved page (=name of image). By clicking the name, you go to image upload page where you can browse to storage location of image on your pc and upload the image into MW. After that image is visible on page where you created the image link earlier.
