Pdf... how to make a pdf (first) page visible in desktop

[Ran]

Hello,
I am using Linux Lite & updates but now when there is a pdf I only see the red pdf adobe mark (icon), but
in the past I saw the first page of the pdf visible and not the red icon and that was ok...
I don't know how to make it the way it was...???
Can someone help me ?
Thank You,
Fred

If you mean a thumbnail view, try this.
On a File Manager (Thunar) window

Click View and ensure 'View as Icons' is set
Then
Click Edit -> Preferences
In the 'Display' tab check the 'Show Thumbnails' selection
If set to 'Never' try changing to 'Always'

Thank You, did that... nothing did change...
Greetings,
Fred

Not sure which version of LL you are using however I'm still using 5.8 and following Steve's advise I checked my settings and they are as follows - I hope this is of some help to you.
