add support for Image note!!
currently Mindmup does support attaching Images
but from my experience, it's only useful for icons of 50 pixels in size!
because large image would mess up the look of the map
so I suggest adding what I call "Image note"
when adding them, they would not appear on map, instead it would add a tiny interactive icon just like when adding notes
when the user click on it, the Image would appear just the like the note would appear
it could be also done by making adding image inside the note possible so that notes would three types:
1- note contains only text
2- note contains only image
3- note contains both images and text
