Probably, if you change setting on buttons block by removing insertimage

from

buttons: [ 
     { type: 'push', label: 'HTML Link CTRL + SHIFT + L', value: 'createlink', disabled: true }, 
     { type: 'push', label: 'Insert Image', value: 'insertimage' } 
] 

to

buttons: [ 
     { type: 'push', label: 'HTML Link CTRL + SHIFT + L', value: 'createlink', disabled: true }
]
