Gray Image


With this shortcode you can display gray images. Just embed an image tag into a grayimage shortcode and the image will appear grayed out. The color image becomes visible when the mouse hovers over the gray image.

Note: The grayimage shortcode uses canvas element for the grayed out effect. Unfortunately, the same origin policy prevents access to cross origin image data, so the grayimage shortcode only works for images located in the same domain as the HTML page which uses them.

For example:

[grayimage]<img src="myImage.jpg" width="200" height="200" />[/grayimage]

startopac The opacity of the gray image.
endopac The opacity of the color image.
