* In a weirdly way:
The images that before were rendered with padding: 5 px, are still rendered with that padding style. Rest of images has now the padding style I've applied in style.css that I've modified to padding: 4 px to see the effect... But now is 5 px.
Anything that was written as <img style="padding:5px" /> will still have 5px padding, because the HTML overrides the CSS file. Remove the padding from the inline style to get it to behave like everything else.
