I think this is what you are looking for (Especially the "Tip" part of the article):http://resources.arcgis.com/en/help/arcgisonline/index.html#//010q000000n0000000This plus the ArcGIS/Collector app for your device (http://resources.arcgis.com/en/collector/) would let you attach images to your newly created points.But for this you need an organizational account.Hope that helps!
