General Support: Error 500 Rejecting Certain JPG's

For what ever reason I can't seem to get plogger to accept certain JPG's even though they're from the exact same scanner (source).

I tried the browse function to get those JPG's and again the same error showed with the pictures not visible. I tried renaming them to see if it was redundancy and again it wasn't the file name.

Fresh install and again the same files produce the very same issue.

What might cause plogger to reject photos when their file format is JPG and only around 600KB?

I noticed that when those certain photos didn't show up in the gallery it still left the file name of them at the top of the page. When I go into Manage in the administration panel to go try to delete them I get a

I went back in to try to re-upload the same file that's missing and it gives me the same error on the next page. I click refresh and it says
