Copying images in XLS 2010

I feel like a dinosaure... I just switched to coding VBA in Excel 2010 from 2003 and I found myself lost with some "simple" things. I would appreciate your help.

Problem 1

Originally, I had an Excel 2003 spreadsheet with some images, lines and textboxes that I copied and pasted in Powerpoint 2003. These objects were pasted in a newly created slide an they remained separate objects, i.e. images, lines and textboxes.

I switched to Exel 2010 (still PowerPoint 2003) and I found that all the objects are grouped and pasted as a single image. I tried different PasteSpecial options with no sucess.

Problem 2

I have one sheet where there are many images, then I select some of them, and one by one I copy and paste them in another sheet.

In Excel 2003 this works fast enough but in Excel 2010 it takes at leats 4 times longer.

I think a solution to #1 is to select ranges all at once and paste them, like:

Sheets(1).Shapes.Range(Array("img1","img2","img3")).Copy
Sheets(2).Paste

But I cannot automate it. For example, this won't work even if I have "the same" string:

myStr=Chr(34) & "img1" & Chr(34) & "," & Chr(34) & "img2" & Chr(34) & "," & Chr(34) & "img3" & Chr(34)
Sheets(1).Shapes.Range(Array(myStr)).Copy
Sheets(2).Paste

How can I do this?

I'm still stucked with this... I thied the following without success:

Code:

---

    Dim my_range As Variant
    Dim test() As String
   
    ReDim test(4)
    For i = 0 To 4
        test(i) = Cells(i + 1, 1).Value
    Next i
   
    Set my_range = ActiveSheet.Shapes.Range(test)
    my_range.Select

---

It says "The specified parameter has an invalid value". Any idea how to solve this? I would expect it to be quite straightforward but it seems it isn't. Help will be much appreciated! Thanks.
