How to show pictures in popup only?

[bluemi]

I would like to avoid the intermediate size which I know how to do. What I don't know is how to force all pictures to be shown in a popup in original size only, as normally you get if you click on the intermediate size. Any suggestions?
Thanks!

Try "from thumbnail to full-size pop-up (skip intermediate page)", "LightBox JS for Fullsize Popup Image" or "GreyBox Popup Window for Fullsize Images"

Thanks, will try them.
