InDesign: Script for exporting layers to jpg

This Works

Sadly the size of the Layer is to big. The whole site gets exportet to a jpg, but not only the LAyer it self. The size should be as the Layer size:

How it i s with this script:

How it should be:

I have a Script which exports the selected layers, but if i select more than one layer they're grouped an are exported as one jpg. Also the layer name doesn't work:

Hi Mike, 

Thanks for your fast reply. I've already tried to use that Script to change it how I needed it to work but couldn't finish it. Im Working on a new one.

I'll try your suggestion under this entry right now!

Hero!
