Connection of a set icons (imageset) for favourite editor Bueditor
1) We connect the module bueditoricon (depends from imageset and bueditor)
2) We add necessary imageset (mysite/admin/settings/imageset)

• Name: bue_icons; Size: 18x18; Orientation: Horizontal

3) We add necessary styles for 3х conditions (mysite/admin/settings/imageset/selectors), for one condition - one line

• CSS selector: <empty> Outer name: Bueditor icon; Weight: 0; Imageset: bue_icons; Variant: 1
• CSS selector: <is>:hover; Outer name: Bueditor icon; Weight: 1; Imageset: bue_icons; Variant: 2
• CSS selector: <is>:active; Outer name: Bueditor icon; Weight: 2; Imageset: bue_icons; Variant: 3

4) In options of editor Bueditor (mysite/admin/settings/bueditor/*) In a column icon it is chosen Caption and in contents we enter sequence name:index;
Where name - name Imagest'á (in our case bue_icons), index - number of a picture (since 1).

Something will turn out similar to it:
