Custom Button icon doesn't work on debian stable

[alansarkar]

Trying to add a local custom downloaded icon for fbpanel button. Like the following
button {
icon = /path/to/icon.png
tooltip =
action =
}
Tried ways around it like using svg ,.ico or few other things fbpanel can't seem to view the icon.

From looking at this comment I have discovered that the syntax is actually image = /path/to/icon.png. Great program this one, but needs better documentation.

By the way, you can find all the customization keywords by grep -r XCG * in the source code.
