WinHelp understands only two graphics formats: WMF and BMP. Graphics in other formats must be converted. Although it may seem that other formats such as GIF work for WinHelp, actually any format other than WMF or BMP is converted by the WinHelp compiler, using a Microsoft Office filter; not the best process.
If your document contains embedded graphics (copied into FrameMaker instead of imported by reference), Mif2Go can export the embedded graphics in their original format; see §29.2.3 .
To exclude graphics entirely, or display only graphics file names, see §220.127.116.11 .
