every image that you want to use in your vst MUST be attached (showing) for at least one widget... so if you want to use various (say) slider widgets then you will need hidden sliders each one with one of your desired image strips.
Wait is this still a thing? I just moved my images from the respective expansions into the project folder and I'm getting Missing errors...
What if you just load images into pool one by one? Engine.loadImageIntoPool( string id)
I really think brute-forcing like this should be possible... I don't want to have to make 16 extra invisible panels just to have my jpgs included in the binary...
Edit: Yep just tested and it resolved my mystery errors... still think making a bunch of panels is an ugly way around it but
