The answer here is yes and no.Yes
you can create a link to the trash, but No
it will not show two images identify when it is full.
To add the shortcut:
Right click on the Circle and choose: ADD >File, Folder or Special Item
This will bring up a new Item Settings window:
In this window you may name the Item anything you wish, we will just name it "Recycle Bin" for now.
In the "TARGET" Area go to "Special"
Click on the "Special" Button and you will be given an extensive drop down list of choices.
Go ahead and Choose/Click on Recycle Bin
Once you have made this selection, choose/Click "Finish" Button at the bottom.
Voila....You should not have an Icon for your Recycle Bin
You can now change the Icon to what ever suites your taste and desktop best.
