I have converted all my PNG format pictures (back) to TIFF. I have been using this format in the past, before I put the pictures online. Since the TIFF support in web browsers is close to non‐existent, I decided to use PNG until I found a better solution. Nowadays computers are much faster than they were in the past, and it is finally feasible to convert TIFF to PNG on the fly for web display, albeit with some delay when processing very large images.
Thanks goes to Bob Friesenhahn for his valuable input regarding TIFF technicalities, and his role as the driving force behind the excellent GraphicsMagick software package, which I find much more stable and bug‐free than ImageMagick, which should perhaps be renamed as “ImageTragick”? Just kidding.
