Thread:Extension talk:WYSIWYG/Rich Media Extention and Image Inserting Error/reply

Hi there. You are right, CKEditor allows pasting images into html as data URI, but mediawiki doesn't know how to handle it. There is an open issue about it: Issue 15629 - Pasting images from clipboard into ckeditor is misleading You have to upload image file to your wiki to be able to assign a link to it. You don't have to install RichMedia Extension for uploading simple images. Uploading is done on a special wiki page: Special:Upload. After you have uploaded your image you can select it in WYSIWYG image dialog. Just start typing your image file name in the "image file name" field. HTH.
