Reference Image Column from another sheet

[NotMat]

Hi all

I have an image column in 'Sheet B' that needs to be mirrored in a column in 'Sheet A', based on the key column.

I have a column in Sheet B that is a Key in for each row where it obviously links info into Sheet A. I used REF type columns in Sheet A to bring in other info from other columns from Sheet B, no problem. E.g [KeyInSheetA.ColumnInSheetB]

However, it won't let me REF the image column in Sheet B, into Sheet A. It says it doesn't match the expected column type of REF. 

Does anyone have any advice?
