How to removed external image cache

I have a function in my app that allows a person to see the existing default image of a video and then upload a new image to the external repo. 

I use the image control to display the image but after user uploads a replacement image, they cannot see it in the display as there is a 1 week cache on the image control that does not allow me to remove or change. Do anyone know how I can remove that caching?

Hi Tivity,

that property is only valid when the image is fetch from the database (Type = database).


So that is why it is "greyed out". Thank you, that answered my question.
