Disable button when image is not finish uploading?

[Korn_Tris]

Hi. I would like to know if there is a formula to disable button before image finish uploading

like in the photo it’s uploading but my button is still available for push. I want to disable it until upload is done

I create the below, but the moment there is part of the image loaded (I guess that how it works) it is no longer blank, so the button is disabled for a rather short moment.

I have tried this one before but the button is still available even the upload is not finished

there is no clean way to solve this issue properly, I created this one and with some tweaking it may fit your purpose
