The pictures included inside a Bible are NOT a part of the Bible itself. I doubt that any drawings or paintings, created at that time, for inclusion in a book, would survive the just-under2000 years it would have to have survived.
The Bible itself is private revelation…which ended with the longest-surfing apostle, who may have lived to the age of 120. So Medjugorje, and all other apparitions, approved or not, are not a part of the Bible, and never will be!
You seem to have a very active and inquiring mind…and, seem to be searching for truth. May your search be a productive one, an interesting one, and a (relatively) short one. Don’t be afraid of asking questions here. But, for serious ones, you should be consulting your priest, and any health professional, or spiritual director he recommends!
