 Handles HTML output (only) for \helpref{wxRichTextCtrl}{wxrichtextctrl} content.
 
+The most flexible way to use this class is to create a temporary object and call
+its functions directly, rather than use \helpref{wxRichTextBuffer::SaveFile}{wxrichtextbuffersavefile} or\rtfsp
+\helpref{wxRichTextCtrl::SaveFile}{wxrichtextctrlsavefile}.
+
+Image handling requires a little extra work from the application, to choose an
+appropriate image format for the target HTML viewer and to clean up the temporary images
+later. If you are planning to load the HTML into a standard web browser, you can
+specify the handler flag wxRICHTEXT\_HANDLER\_SAVE\_IMAGES\_TO\_BASE64 (the default)
+and no extra work is required: the images will be written with the HTML.
+
+However, if you want wxHTML compatibility, you will need to use wxRICHTEXT\_HANDLER\_SAVE\_IMAGES\_TO\_MEMORY
+or wxRICHTEXT\_HANDLER\_SAVE\_IMAGES\_TO\_FILES. In this case, you must either call \helpref{DeleteTemporaryImages}{wxrichtexthtmlhandlerdeletetemporaryimages} before
+the next load operation, or you must store the image
+locations and delete them yourself when appropriate. You can call \helpref{GetTemporaryImageLocations}{wxrichtexthtmlhandlergettemporaryimagelocations} to
+get the array of temporary image names.
