Does anyone else have the issue where the Juicebox crashes after a few hours in Picture Display Mode?
This didn't start happening until recently. After an hour or so, the screen simply freezes and the Juicebox becomes unresponsive. After a reboot, it's back to normal, but then not long after it crashes again.

Heat issues perhaps? Is this still in its normal shell?
Does it just display the same image all the time, black screen, or snow crash? Black screen crashes might be a trouble with the battery terminals expanding from heat.

What are you using for power? Make sure your wall-wart (assuming you're not using batteries) can deliver enough current. Don't remember what the rating of the official AC adapter is but 3/4 to 1 amp is probably enough.
Also if the voltage is much higher or lower than the expected 4.5V it could stress the JB's internal DC-DC converter causing it to overheat.
FYI -- I've had a JB running in picture mode for the past 4-5 hours without a crash.

Well I'm using the standard power adapter that was sold for the Juicebox.
And I've had this Juicebox running fine for the past week (continuously) until this started happening. It's not in its original case, right now it's sandwiched between two sheets of acrylic.
Should those black terminals that have a small ring at the end of them be grounded? Or are they just for grounding the case? Because I noticed those three terminals attached to the original casing when I was taking it apart.

Yeah, those are for connecting the conductive coating on the case, and copper foil on the display, to ground for RFI/EMI suppression. The JB should work fine without them.
Most likely you have a bad JB.
But to make sure you can try to eliminate the other parts of the system;
If you don't have another AC adapter a set of fresh batteries should last long enough for the problem to appear.
Clean the gold fingers on the MP3 adapter with a pencil eraser (use it lightly - there's not much gold there).
Try another SD card.
You could confirm heat being the problem by temporally running the JB in a refrigerator (or the freezer) -- if your wife/family can tolerate something like that!-)
Alternatively, point a fan at the JB to see if it runs longer.
