Commented Unassigned: pictures inconsistent when pasted into htmlextender [27796]

When I use the htmlextender in a page, I often try to paste html from wikepedia or other webpages into it. So I select a portion of those webpages, and do Edit/Copy, and then I paste into the htmlextender. Other times I copy and paste from emails that I get (I use Windows Live Mail). I find that in some cases, pictures do get transferred. Other times, there is just a blank frame where the picture is supposed to be. Does anyone know why this happens?
Internet Explorer seems to block pictures completely (in the extender).
Thanks.
Comments: We couldn't reproduce the issue. It seems that you are using the old AJAX Control Toolkit version (ToolkitScriptManager was removed in v15.1). Please update to v15.1 and let us know if the issue persists.
