Image Library Not Functioning on my Linux Laptop

All my images load just fine on my windows desktop, but my laptop running Linux Mint 18.3 almost every image loads as broken.  Does in Firefox and Chrome.  All images are .png or .jpg.  Only extension I'm running is add block, but Roll20.net is whitelisted.

Have you tried disabling AdBlock entirely (or opening Roll20 in an incognito window) to completely verify?

Tried both incognito window and removing add block.  Still get this:

I'm at a loss for what could be causing this, but luckily I'm not a Dev.  ;)  Would you please carefully work through the first three steps of our guide to Solving Technical Issues ?  I doubt #3 will help, but you never know!  We'll need the log for when the Devs are pinged (which will happen if you report that Step 3 does nada for you). Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you!

It appears to be a pathing issue.  For whatever reason even though the files have been uploaded it is still looking for them on my locale machine.  I verified this by logging in from another Windows PC and sure enough they are all link dead.  This is very odd behavior for files that were uploaded first.
