Paste Picture Link option in Excel

I used the "Paste Picture Link" function in Excel to paste a range of cells to another location in my spreadsheet. It has been working fine (I could select the "picture" of the range, and drag it around just like it is supposed to work). Now, I cannot select the "picture". And, if I try to use the "Paste Picture Link" again in the same worksheet, the option is greyed out. Any ideas on why the option would stop working/become unavailable?

Thanks in advance!!

Looks like I found my own answer! If the workbook is shared, the picture cannot be selected. That's a bummer but at least now I know what the issue is.
