我想在我的小程序中添加 615,50 的图像。图片名称是 logo1.jpg 。但以下代码仅打印 d 图像.. 当我编译然后使用小程序查看器运行时。只有图像 logo1 显示在 d 点。其余代码不起作用。但是，如果我删除图像。然后代码工作正常。我认为paint() 函数存在一些问题。如果我使用 ImageIcon 然后将其添加到标签中并将该标签设置为该位置，那么它在 appletviewer 中可以正常工作，但是一旦我在网络浏览器中打开它，就会出现 IO 错误
"access denied("java.io.FilePermission" "logo1.jpg" "read" )。请帮忙。图像大小为 126,126。

每次我使用paint方法时，只有paint方法有效，其余代码无法正常工作。即使我使用paint() 方法画一条线。然后也会发生同样的情况。
