I want to Thank everyone for your suggestions. It got me thinking about the problem and as I said I “assume” Linux Mint was the problem. I will give an update later, but first I wanted to respond to all the helpful suggestion. I truly appreciate each response.
@nevj – Yes I use the file manager. In Mint it is Nemo. I only use the terminal when a GUI does not do the job. Yes, I can see the files names and I can copy the files to the desktop. It is only when I try to view the jpg when I have the problem. Both on the USB and on the desktop the pic will not display. Also plugging in the USB either before or after boot did not change anything.
@daniel.m.tripp – Your’re right. It is a Sony Memory Stick. So even tho it is a flash drive, it can not be plugged directly into USB port, but it needs to be plugged into a USB reader that compatible with the Memory Stick.
@artytux – The format of the pics are jpg. I copied the files to another flash drive that would connect directly into the USB port and got the same results. The pics would not display.
@kovacslt – Here are the last few lines from dmesg.

@4dandl4 – Good idea. Below is what happen with the copy and an update.
@clatterfordslim – Thanks for the link. I already have 2 USB reader for the Memory stick. The problem happens on both readers.
Update.
Like I say all the response that were posted got me to thinking more about the problem.
I got my laptop out that also has Lint Mint installed on it. The Memory stick worked fine!
So that would tell me Linux is not the problem. Right?
I copied the files to the SSD on the laptop and then copied them back onto another flash drive that could be plugged directly into the USB port. I again got the same error.
So now I’m at a loss. I know the USB ports are working. I use them for external HDD, I can read other flash drives. I notice there was an error message at the end of dmesg, but Windows and Linux on my laptop displayed the pic.
The only thing I can think of now is that either there is something different about the PC or something different with Linux on this PC that is causing the problem.
I also installed Gpicview and it can display the pics. So now does that mean something is wrong with Nemo on this PC?
