What is the best way to create slides for projection from digital photos. Two ways I have considered are to use Power Point, or to use the transparent material meant for use with copiers-print on that and then cut them to 35mm size and mount them in 35mm mounts. The Power Point method would limit use to having a portable computer and projector available.
Have you explored online slide services. Search Google on "35mm slides jpg powerpoint". There are many professional companies who can convert jpg and powerpoint files into 35mm slides at a reasonable price. It just so happens I own and run one of them, IQ Imaging, but there are many others as well.
