I have heard that it is common these days for digitized images to be made when a Sefer Torah is written, though we don't have any such images at the shul I attend.
Having yet to find a tikkun that prepares me for the "visual-spatial" challenges I'm sometimes encountering when I lein in shul, a repository of real images seems like it would be most helpful for preparing myself for the diversity I can expect to encounter. Where would I find such repositories or other useful sources?
