推荐答案

请不要使用txt来说话，那是为了帮助而不是程序员.

不，您不能使图片框指向链接.您需要下载图像以在本地显示，除非您在应用程序中放置了Web浏览器控件，然后在其中放置了html控件(链接到该图像)的html.图片框需要图像，而不是链接.

Please don''t use txt speak, that is for retards, not programmers.

No, you can''t make a picture box point to a link. You''d need to download the image to show it locally, unless you put a web browser control in your app, and then put html in there that is an img control linking to that image. A picture box wants an image, not a link.
