Updated then pictures all gone when I added them they are now duplicates

I updated Blocs from 2.45 and now my pictures are missing from the assets. I then added them again inserted them back into the pages, now when I look at preview and I am seeing double images on preview but the images don’t show double in blocs. When I remove the image that I added, I see no image on the preview on browser but on opera I can see little small circles where the images appear to have downsized to itty bitty size. I cannot figure out how to restore the images.

That sounds like a bit of a mess and hard to understand without seeing it live. I would be inclined to file a support ticket and send in the project file. https://cazoobi.freshdesk.com/support/home
