Image Placeholder Error

Updated: No new php error but I still have the same image problem as described above.
What I find strange is when I look at the very first post ever created on my site, the NEXT image is there (as expected) and no issue with an image placeholder for PREV image. I’m no coder but this is making me think it may be some conflict with the latest release of WordPress. Also: I noticed this morning that my CPU usage is going crazy. I am going to deactivate WPNPNavi until I can find the cause. Thanks for looking into this. Respectfully.

I did just that before asking support. I also deleted the two images I used previous and replaced them with new images. Plus, when I navigate to other post that do have a previous and next post, the images displayed fine. It may be some conflict within my setup…I tried using the plugin WP Rollback to try a previous version of your plugin but it says your plugin does not contain anything “to latch onto” to rollback to previous versions. I am currently using your plugin without my own images but in a perfect world using my own images it preferred. Again thanks for your time!
