While we’re at it, posting the width of pictures is a bit confusing.

“width=500” does not have to be in quotes. I notice that you’re now posting “width=50%” , which seems new and depends on the width of each picture, right?

[Hebrews 11:6]

If you specify width=500, you're producing an image exactly 500 pixels wide. A full computer screen is about 650. But many are using smaller screens, on phones and tablets, and bigger images get cropped.

Using "50%" or 90% avoids that by tailoring your image to every screen. It does not "depend on" the picture's width; rather, it fits the picture to the viewers' screens.
