Is this the PhotoStructure for desktops browser, or a browser on a different machine?
If your home LAN network is involved, know that I had a similar experience due to my orbi router: it had a âddos protectionâ setting that dropped requests/thumbnails that I had to disable.
Even after disabling it, most thumbnails would show up, but I still had some broken images. I found that the router just wasnât up to the task of serving hundreds of high velocity requests. I had to switch to my old Asus router running open source firmware and the thumbnail loading issue went away.
Iâd first run the web service with debug logging, so you can see requests as they happen. I suspect your webserver isnât seeing most requests.
Iâd also open the developer tools in your browser, and select the network tab.
Iâd also try using an Ethernet connection through a known-reliable switch rather than Wi-Fi.
I had to replace an aging cat5 cable and older switch before my nuc could reliably access my NAS. (Itâs actually why PhotoStructure has import retries built-in).
If this isnât network related, given that youâre on Windows, know that most other antivirus software can wreak havoc with PhotoStructure: only Windows Defender is supported: Antivirus Bitdefender identifies PhotoStructure as a Malware - #2 by mrm
If youâre running only Windows Defender, on localhost, and seeing this issue, please email me debug logfiles: PhotoStructure | What are in my logs and error reports?
