The browser does not use alternate text when copying content that contains images. For example, select and copy content containing an image. Paste into another application (like Microsoft Word) as "Unformatted Text" or into an application (like Notepad) that only supports plain text. Alternate text (the value from of the image's @alt attribute) should be inserted in place of the image. Instead, the browser inserts nothing in place of the image. This means content is lost when pasting into other applications. This can affects comprehension. And this behavior does not encourage the use of alternate text, which is a primary accessibility feature in HTML. To reproduce the problem, render the following markup: <h1>I <img src="heart.gif" alt="love" /> you!</h1> Test page with the above markup: http://html4all.org/staging/a11y-bugs/1000/love.htm Select and copy the content. Paste it into an application like Notepad. The result is "I you!". Instead, the result should be "I love you!". Example of products that correctly support copy/paste of alternate text: - Firefox - XStandard WYSIWYG editor - BlueGriffon WYSIWYG editor In order stress the importance of this bug and to assure you that the recommended way of fixing the bug is appropriate, this bug is co-signed by the following accessiblity experts: - Alastair Campbell - Andrew Downie - Denis Boudreau - Everett Zufelt - Jason Kiss - Jim Byrne - John Foliot - Joshue O Connor - Laura Carlson - Leif Halvard Silli - Nigel Peck - Roberto Scano - Roger Johansson - Vlad Alexander This bug report comes from the community led a11y bugs project here: http://html4all.org/staging/a11y-bugs/
