The benefit of using the Photo Gallery [the long method] is you can choose Medium or Full for posting in a thread so it isn't over powering.
Medium Image Max Width/Height
If either the width or height exceed this value then the larger sized property will be scaled to this, with the other being proportionally scaled.
Default: 480, however Forum is set to 300 pixels
Full Image Max Width/Height
If either the width or height exceed this value then the larger sized property will be scaled to this, with the other being proportionally scaled.
Default: 1920, however Forum is set to 1200 pixels
