Sorry for the blank post,

I clicked to fast,

you can check to see if the picturebox is empty like this:

if picturebox1.image is nothing then
msgbox("I'm empty")
end if

It's Image property will not be "Nothing".

\\\
If Me.PictureBox1.Image Is Nothing Then
...
End If
///

Alternatively you can use the 'IsNothing' function.

With = you can see if a value of a property = Something

With "Is" you can see of the address of a referenced object is Something

I hope this helps,
