Try the preview with ctrl button pressed, this reloads from scratch the preview, it will take a little longer to load.

If It still not loads correctly try in the preview top right pulldown button and select a browser and see if one of those work.

The problem is preview during editing.

Géza, yes, but did holding CTRL down whilst clicking preview as Andre suggested fix the problem, or did you need to preview in an alternative browser?

It's best to edit first then preview, continue ediiting, then hit preview again.

If you have set in the preference to update the preview during editting it only does so after hitting save or next button, then you don't need to hit preview and preview will be updated.

But your screen will be gone so the first method I like to use personally, because else if not correct you need to open object again. it is not a live update function.

Have you seen the picture I attached (Justified Gallery.jpg)? The problem is not the browser preview, but when I put pictures in the gallery.

Géza, apologies. Yes I have now looked at the image provided. This is a case of Incomedia removing functionality, I am not sure if it happened around the transition from v12-v13, or v13-v14. The decision to show generic images rather than thumbnails of the actual images is frustrating, annoying and time consuming. When I queried this I was informed that it was a decision of the developer of the optional object.

The only recommendation I can make is to post the request for the return of the real thumbnails in the Justified Gallery layout screen as an idea.
