pedroantonio,
All the code in the DCL is there, just take a look at it. For example the DCL starts out with a ROW (the ROW is not terminated until the end), then there are 2-columns within the ROW the 1st column contains the IMAGE and the 2nd boxed_column contains the paragraph. You should be able to figure this out if you study what is already there.
It seems you want to eliminate the ROW and just have 2-columns one above the other instead of beside each other.
You can load the DCL in the Visual Lisp Editor in ACAD (vlide) and make the adjustments then preview very quickly.
