In Zoom Konrad Papala توسط

Enlarge photos and videos "inline", using shift + mouse wheel.

This extension works "inline", i.e. images are not displayed in a popup - instead they are enlarged exactly where they are.

When zoomed in/out, you can drag the image around, if necessary.

It's open source (on github)

If you have any suggestions, please don't hesitate to reach me on konradpapala@gmail.com or file an issue on the github page above.

New in version 1.3: a shortcut for bringing the element to the front, in case it's covered by other elements ( https://github.com/kpion/inzoom/issues/5 )
