HTML allows resizing of an image using height attribute in <img> tag.
but firefox rendering of a resized screenshot image make text content on the image not readable.
we need to improve this.
Current algorithm may be faster, so this rendering mode is OK when displaying the page.
But I feel when processor get time img should be re-rendered to make contents more clear.

See attachment image resized to 50% with MSPaint.exe is very much read able.
