As far I know in Excel (also with VBA coding) it's not possible to get the original picture out of a comment. Therefore you would have no chance in LabView too. The most popular workaround in VBA is to copy comment as Picture to clipboard, but you get it (including text) in the size of your Excel comment. Translated to LabView:
Read Images from Excel
in LabVIEW General
