Thanks! It is done, same URL now provides choice of TIFF or JPG. But it actually shouldn't matter in terms of your hardware: TIFF is just a graphics format, albeit one typically used at full quality. The compression would presumably be the relevant thing. One of the options TIFF provides for compression is (presumably lossy) JPEG compression, which should offer the same quality and the same compression, but require more calculation. I had used PackBits compression, which is run length encoding for those of you who know what I mean, because the 2 best options for TIFF compression have problems: the best, deflate, is not widely deployed, and the second-best, LZW, is encumbered by a patent held by Unisys, who apparently reneged on an agreement about enforcement of it. But none of this is really relevant to Pittsburgh Railways except that I learned about it while dealing with digital maps and aerial photos while tracing local rail lines. -D -who just came from a large family gathering for my grandmother's 95th birthday. ]
