I have to set the (picture-)size of a jpg image to 2 (instead of 20) in order to get 20 %text size, whereas the same eps image set to 20% gives the correct 20 %text size.
You wrote the size is 2. What unit did you use? text%, page% or what?
When you have problems with text%, then try another unit (col% works fine on LyX 1.3.2).
