Steps to reproduce :

Add a new column on Test table, with
Reference = Image
ColumnSQL= (SELECT CASE WHEN C_Currency_ID = 102 THEN (SELECT AD_Image_ID FROM AD_Image WHERE Name = 'Account') ELSE (SELECT AD_Image_ID FROM AD_Image WHERE Name = 'BPartner') END FROM DUAL)

Add the field on the window
Remove 'large fields' on the grid view (such as CharacterData).

Then open the Test window
In single mode, the image is correctly displayed, but if you swith to grid mode, height is too important.

In previous version, the height was better (reduced)

Just tested on test.idempiere.org ; you can use attached 2Pack (exported from there)
