Help needed - images not displaying in OpenCart v2.1.0.1

Hi guys - I've been running v2.1.0.1 for some time now with essentially the default theme (some color modifications, but that's it). This morning I logged in and found that some of the product thumbnails are not displaying correctly. Additionally, for the few that do display, if I click on the thumbnail to enlarge, I get an error saying "The image could not be loaded.". I've attached a screenshot showing the issue, and as of 7:51AM ET on 23-Oct, you can see it at www.advmotorrad.com.

I checked on my test site (hosted on the same server) and it seems to be working fine. My error log was pretty good sized, so I saved and cleared that, and cleared the image cache...neither helped. Most of the error log is filled with logging by the USPS app, but this error keeps repeating...maybe it's a cause?

I've got a ticket in to my hosting company, but I don't think it's necessarily a hosting issue as my other site works fine. Any ideas for assistance would be greatly appreciated!

Thanks...

One more update - I also cleared the VQMod cache and the /system/storage cache...no change. There is a new error showing in the log:

2018-10-23 8:01:37 - PHP Notice: Undefined variable: languages in /home/advmotor/public_html/admin/view/template/module/CachedImages.tpl on line 50
2018-10-23 8:01:37 - PHP Warning: Invalid argument supplied for foreach() in /home/advmotor/public_html/admin/view/template/module/CachedImages.tpl on line 50

I have a small logo to replace the default OpenCart "cart" icon in the browser tab. What's strange is that if I hit refresh, the logo icon appears momentarily, then disappears and is replaced by a "folded page" default icon.

Thanks...

Well, something like CachedImages.tpl and/or perdisc does not exist in
a default Opencart. In addition, your Images are NOT titled according HTTP Spec's,
you have empty WHITESPACE Gaps in Image Titles and Image Directory Names as well. In addition to some REDIRECT Problems, possibly based on wrong .HTACCESS Settings.
So, better start again from scratch!

Thank you IP Cam! I appreciate the help, even if the answer just made me turn green. I now recognize the importance of no spaces in file names; unfortunately, 99.9% of the pictures on the site may have spaces. This has been running this way without issue since 2012, so my guess is that something has changed on the server side that no longer will allow it to work.

I can download, change, and reupload all the files, but pretty sure it will simultaneously break every single product image, as Defender S10 1.jpg is different than Defender-S10-1.jpg. Any possible way to do the same bulk name replacement within the OC database? The thought of having to rebuild 500+ products individually is making me nauseous.

Thanks...

Jason

Well, you did not answer the question about those two Files, unknown to me,
but below, you find a list of Extensions, possibly beeing of help, to get the images
titled correctly. In addition, please show the .htaccess File REWRITE CONTENT,
looking similar to this: Ernie
