Since upgrading to OSX Mojave none of my images on desktop or in finder are showing their preview image. ***** because I rely on this for work. The issue resolved itself once by restarting computer but since then it hasn't worked again 😟
MacBook Pro (Retina, 13-inch,Early 2015), macOS Mojave (10.14)
I have also had this issue with Mojave, Icons will start to load and then stop.
Reinstalled OSX with a clean fresh format, issue still persists.
Updated to 10.14.2, issue still persists.
The only way around this is every so often, in terminal, type qlmanage -r
Then close the window and re-open, the thumbnails should load up - its a temporary fix you will start to notice again icons won't preview, then just run the same command in terminal again!

I have the very same problems, sometimes I get preview back but more often than not I have the same.
I am not running Sketch and no-one seems to have an answer - reinstalling High Sierra. Unless there is a problem.
I also uninstalled dropbox - no effect.
I have the same problem on Macbook Pro 13 inch 2017. The temporary fix recommended by CCabra is very helpful. Apple needs to fix this.
Thank you. This temporary fix works perfectly.
