Simple method for generating PDF files for output/download, based on pretty much just image content

Like subject line says, while have come across various modules/classes for trying to handle all sorts of involved PDF output file generation, I pretty much only need/want to spit out a PDF file containing something like a single image file, or maybe one per page, and, yes, suppose, possibly with PDF-specific forms of write-protection enabled - but that bits not necessarily too important.

TIA
