picture1.picture=loadpicture("\u56fe\u7247\u8def\u5f84")
picture1.autosize=Ture
picturebox有个属性，AutoRedraw 改为true 就能在form任意更改大小了
'试试我这个可以对图片剪裁的
Private Sub Command1_Click()
Dim SaveMode As Integer
'为图片框保存当前的 ScaleMode。
SaveMode = Picture1.ScaleMode
'复制picture1的图片到clip1里
Set PictureClip1.Picture = Picture1.Picture
'获得裁剪区域的 X 和 Y 坐标。
PictureClip1.ClipX = 0
PictureClip1.ClipY = 0
'设置裁剪区域的范围（用像素）。
PictureClip1.ClipHeight = 50
PictureClip1.ClipWidth = 50
'设置图片框 ScaleMode 为像素。
Picture1.ScaleMode = 3
'为图片框指定裁剪位图。
Picture1.Picture = PictureClip1.Clip
'使图片框的 ScaleMode 复位。
Picture1.ScaleMode = SaveMode
End Sub
其实我不怎么懂VB，但是你传图片进去之前可以在画图器里编辑下大小么。。。
