Image on Whiteboard easily erased

[beth7808]

Hello. I tutor math, so I frequently need to put an image of the problem up and then use the writing tools to show steps etc. However, the eraser tool will usually erase the image first. Undo does work, but it always puts the image back as the top layer. Other whiteboard apps have images and post it notes not erasable with the eraser tool and require the selector tool and a delete button. Something like that would be better.

Secondarily, I would like to be able to paste images in during the live whiteboard. Currently I have to have the whiteboard open twice. Thanks!
