Hi

It hasn't got anything to do with L-R/R-L feature. The picture in its size of origin probably just doesn't fit on the sheet, therefore the ratioaspects get lost.

Enable the columns beyond AB and most probably it will do (otherwise you may enable a couple of rows as well). The other option is, to insert the picture on another sheet, arrange the seize there according to your selection, and copy it to the space desired.
