如果它是链接图像，请用新文件覆盖链接图像文件，或将链接指向新文件.

If it's a linked image, either overwrite the linked image file with a new file or point the link at a new file.

或者，如果形状是图片填充的，则可以用其他图片填充它.如果图片的比例与形状的比例不匹配，则可能会使图片失真.相反，您可以根据需要更改形状的长宽比以匹配图片的长宽比.

Or if the shape is picture filled, you can fill it with a different picture instead. That can distort the picture if its proportions don't match the shape's proportions; instead, you can change the aspect ratio of the shape to match that of the picture if need be.

要更改图片填充，请在osh中引用形状:

To change the picture fill, assuming a reference to the shape in osh:

With osh.Fill
    .UserPicture ("C:\path\to\picture.jpg")
End With

要计算图片的大小，以便可以调整其形状，可以使用外部图像处理软件，也可以将图片插入PPT，将高度和宽度参数设置为-1，然后选择.Height和.新插入图片的宽度，然后将其删除.

To work out the size of the picture so you can adjust the shape to it, you can either use external image processing software or insert the picture into PPT, giving -1 for height and width parameters and pick up the .Height and .Width of the newly inserted picture, then delete it.

或插入新图片，拾取旧图片的大小/位置/其他属性，然后将其应用于新图片，删除旧图片，将新图片移到旧图片的Z轴上.

Or insert a new picture, pick up the old picture's size/position/other proprties and apply them to the new picture, delete the old picture, move the new one to the old one's Z-order.
