I am using LIbreOffice 4.2.8.2 on Ubuntu 14.04 LTS.
I have added three new commands to the standard toolbar. However, when I attempt to add an icon, I cannot. Instead, I get this message:
Per the directions found in LibreOffice itself and mentioned here, I am using 26x26 icons in .png format
Are there particular .png export settings that I need to use? Am I missing a LibreOffice dependency? (It came pre-installed with Ubunu). Extensive googling (2+ hours) has not revealed anything constructive.
I have previously done with with OpenOffice in Windows7 with no problems, but I am fairly new (<1 month) to Ubuntu.
