Extending jrCore Icons
Jamroom Developers
Yep - it's just as easy. Create 2 new directories in your modules img directory - i.e.:
ntYourModule/img/icons_black ntYourModule/img/icons_white
And place the icons inside the respective directory. They should be 64x64 transparent PNGs - one black, one white (the core will handle coloring them if you choose to use a color). Reset caches and make sure the "Reset Icon Cache" is checked and you're good to go.
I'd recommend naming the icons with the module name - i.e.
ntYourModule_checkmark.png
Then you can use "ntYourModule_checkmark" when making the jrCore_icon call.
Let me know if that helps.
