"Image Toobar" is a feature in IE6+ facilitating the handling of images on a page. When the mouse pointer is moved over a picture, the Image Toolbar appears in the top left corner of the image, allowing the instant saving, printing, and emailing of the picture. Fortunately IE allows the publisher to disable this feature. (Disabling the Image Toolbar cannot guarantee you that your image is safe from manipulation)
To disable Image Toolbar completely for all images on a page insert the metatag :
<META HTTP-EQUIV="imagetoolbar" CONTENT="no">
Setting it to "yes" enables the toolbar for all images on the page(This is the default value).
In case you want to enable/disable the toolbar only for a particular image then insert the attribute GALLERYIMG to the image tag :
