Table linking graphics object to a smartform

Hello,

We are changing logos/ bitmap images that contains our address ( because we are moving to another place).

Is anyone aware of a table that links the graphics object to a smartform? For eg, All the texts in a smartform is available in table STXFTX. This helps to have a where used list kind of report.

We are not able to find that can give us a hwere used list of graphic objects loaded via se78.

If anyone could give some pointers, that owuldbe of great help.

Thanks

Ganesh.S
