For DeskI you dont have to use boimage://, it should just be the UNC path pointing to the shared or local folder.
For WebI reports use this in the cell formula editor
="boimg://xxx.bmp"
And set the property read cell content as to Image URL.
If the report is created from the server machine the image is displayed even in Infoview.
How to achieve the same with client installation. What is the path syntax that should be given when deski report is developed from client installation. Because when path of the local system is given, image is displayed in Deski report but when viewed from infoview just a crossed line is seen.
