推荐答案
将图片另存为..."命令?
he "Save Picture As..." command ?
如果您已经注意到，仅当右键单击图片时，将图片另存为"才会出现在IE中.
因此，您需要具有基于单击表单的位置的自定义上下文菜单.假设您在图片上单击它，然后可以获得图片的详细信息.获得图像信息后，单击保存图像功能"，只需在保存事件中使用图像详细信息即可.
If you would had noticed, the ''Save Picture As'' appears in IE only when right clicked on a picture.
So, you need to have custom context menus based on where you click on the form. Lets say you click it on an image, then you can get the details of the image. Once you have the image information, on click of ''Save Image function'' just use the image details to work with in the save event.
