Hi, I'm checking it, and I found that setting src to null makes the browser throw an error: Failed to load resource: net::ERR_FILE_NOT_FOUND (also tried to set to '' but it didn't change anything)
so that doesn't seem the solution Royale should do by default, since apps will be getting lots of errors in browsers console. Searching on the internet people use to remove the image from the DOM or remove from display, I think we can do that. What do others think about it? Also since we are adding ErrorImage.as bead, we can manage it there. So a normal image control only can load an image. If people want to set it to null or empty string and remove it add ErrorImage bead and display the alternative image. Also we could have another "RemoveImageFromDisplay" and "RemoveImageFromDOM" bead that instead of add alternative image will remove from DOM or display or DOM respectively. thoughts?
