Why IMAGE won't open
Most "won't open" issues are format mismatches (the extension says IMAGE but the bytes say otherwise) or unsupported variants (a specific sub-flavor of IMAGE the receiver's software doesn't handle).
Converting to PDF with Image to PDF re-encodes the content into a clean, standards-compliant file. Whatever weirdness the original had, the output of Image to PDF is a fresh, well-formed PDF.
