How do I paste from the browser with images? It worked, then stopped working.

Then, I downloaded another portable version, and there it worked again.

I compared the settings in the working and non-working version, but they seem all the same.

Where is the switch?

There is no switch, it should simply work. If it doesn't please let me know from which browser and web-page URL it doesn't works.

I figured it out already. It was my firewall. :)
