At the narrow width 442px I start with 2 columns 3+9 in a row.
From 646px I increase to 4 columns with picture links in the last 2 columns, i.e. 2+5+3(pic)+2(pic)
When I slide back to 442px with only 2 columns again 3+9 (I don't want to stack 2x2 - so no pic columns) the word "Picture" in very small print appears at the foot of both columns.
I know I'm misunderstanding something about columns, but can't figure out what that is.
Would appreciate any advice on this.
