I want to create a source for several persons in my tree from a family bible. The owner graciously furnished copies of excellent detail in the form of PDF's which are about 30 Mb each! At first, I converted them to JPG's, switched to grayscale and reduced resolution so that each page was less than 4Mb. The free profile system rejected them as too large. Since the entries in the bible are handwritten, fine detail is needed to determine some entries. Hence, large files! I then converted each page back to a PDF and they were accepted but, as PDF's, they have no thumbnail or preview, making the profile difficult to read.
There must be a better way! Suggestions? Many thanks.
