I would like to know what image-type is recommended for the icon in the left-side vertical menu in Finesse.
I follow the guide in Finesse Administration Guide for Finesse 12.0 ETF section "Customise Icons in Left Navigation Bar"
I use the <icon> tag and point to a .png file with transparent backgound with color mode "indexed" (created with GIMP)
It shows up fine in Firefox but does not show in IE11. If I just load the image path in IE the image is correctly displayed, so it's not that IE does not understand the format.
There is nothing in the manual about specs/recommandations for icons.
Any help is appreciated.
