accessing origin info in digital pics that is embedded

hiyaall
I'm new to this and I'm afraid there's not much I can bring to such a forum of generous and knowledgeable folks other than a challenge that I need to solve pronto so I guess I'm trying to cut corners with Faststone and not getting the full value, if it is the right package. Problem = digital photos - currently images in jpeg - no idea what camera but I've been told there is embedded info - date and time of photos taken that I need to see (not when the jpeg was created) can it be done and what do I need to do it?. Second, resolution needs to be very high for me to pick up very small detail. When I use software the screen just pixellates - what would anyone suggest. In return if anyone wants some marketing input for a project I'm sure I can help. Hope this is clear. regards Pete
