Adding preview to folder jpeg

[DNA1010]

I'm using the below in Live 3.0.1

Code:

<img width=40px src="{.if|{.filesize|%item-resource%\folder.png.}|%item-url%folder.png
|{.if|{.filesize|%item-resource%\folder.jpg.}|%item-url%folder.jpg
|{.if|{.filesize|/template/{.!theme.}/images/icons/%item-name%.gif.}|/template/{.!theme.}/images/icons/%item-name%.gif
|/template/{.!theme.}/images/icons/folder.gif.}.}.}"/>

How to apply the pop up preview to both jpg and png like them are in the folder and not affecting the gif?

Thanks

It would be very complicated to explain how to do that... take a look at how image files work.
