How does one send an image of a problem to the forum

I clicked on the image icon and it asks from where, URL or from computer, I click on computer and nothing happens so that I can load an image…what is the secret of doing this? Also how do I make a copy of my problems so that the file can be open to see the problem, how do I render and save it on my desktop so that it is blender file in what format…I see it say PNG?

You have to select ‘from computer’ and then ‘choose file’ right below it. Then navigate to the picture on your disk drive.
It might be a problem with your browser if this doesn’t work for you.

Select From Computer
Browse to the image you want to attach
Select the image
