I have an image logo.png stored in both Resources and Images folder in my VB.NET project. However, this image is somehow not visible for the add-in. I've checked the add-in package (.esriAddIn zip file) after compiling the project and there is no image "logo.png" in the Images folder inside this package.
The question is: how can I include this image to my add in package?
I had similar problems with icons for specific buttons in this add-in, however this was fixed when I used ArcGIS wizard for adding new items to my VB.NET project.
