Hi @Anonymous ,
Attachmened file will display in list like this by default.
It's not supported to change it.
You could check its name when editting one specific item.
If you want to see its image, you need to click on its name.
As an alternative way, I suggest you use Picture or hyperlink column.
These two kinds of column can meet your demands.
Best regards,
