In fact, I use several tips that fix this type of problem:
Current text block settings:
A wrapping of x leading (here: 5,08mm = 14.4pts):
And finally, the image block height is aligned on the grid… If para style with no space before/after.
If space e.g. before, as here (2mm):
I continue to align the Image block on the grid, I count the number of space before on the Image left side (x 2) and increase the image height of 2 x 2mm = 4mm).
Good headache!!!
