问题描述
我想禁用从HTML文件复制图片文件。我已经购买了Activ eBook Compiler禁用左键单击复制，打印和Alt + PrtScr复制到剪贴板的软件，但它仍然不会禁用拖动和放大下降。我意识到知识渊博的计算机用户可以绕过大多数禁止复制的尝试，但我想，至少要让它变得困难。我试过了：
[HTML]< BODY onBeginDrag ="返回FALSE;"> [/ HTML]
和：
[HTML]< img src =？mypic.jpg？ ondrag =？return false;？ /> [/ HTML]
但这两个命令在XP专业版的浏览器（IE7）中都没有任何效果。
任何人都可以提供帮助请？
I want to disable copying picture files from an HTML file. I have purchased "Activ eBook Compiler" software which disables left-click copying, printing, and Alt+PrtScr copying to clipboard but it still doesn''t disable drag & drop. I realise that a knowledgeable computer user would be able to get around most attempts to disable copying but I want to, at least, make it difficult. I have tried:
[HTML]<BODY onBeginDrag="return FALSE ;"> [/HTML]
and:
[HTML]<img src=?mypic.jpg? ondrag=?return false;? />[/HTML]
but neither command has any effect in my browser (IE7) in XP Pro.
Can anyone help please?
