Are you using any antivirus software that may be blocking the images? There have been some reports recently that some antivirus is falsely triggering on HB stuff.
For what it's worth, I am not seeing this myself (and I am not using antivirus either).
Yeah, it's Avast blocking - I just added it as an exception/whitelist but it's still not loading but if I turn it off completely then the pics load.
Previous exception seemed to eventually work but suddenly now back with blocking images from herbiceps cam. Adding the additional exception of https://cdn.herbicepscam.com/ seems to correct it , at least for now.
You can report the false positive to Avast on this page if you want: https://www.avast.com/en-us/false-positive-fi...
(The exact addresses blocked were in the logs under C:\ProgramData\Avast Software\Avast\report, the last time I tested this)
There seems to be a problem with most images on the Herbiceps cam adverts/links on the main pages. Refreshing the page doesn't correct it.. If you click on a broken image on GWM through to the Herbiceps cam page for the individual profile all the images are broken there too, in my recent experience. Same with three different browsers.
