You can capture the entire WebBrowser control to a PictureBox. Use the BitBlt API, passing the dimensions of the WebBrowser (in pixels), and the WebBrowser's hwnd property for srcdc, the PictureBox's hwnd property for destdc. Give the PictureBox control the AutoRedraw property.
You'll have to sort out the image from the rest of the control's contents.
>>btw, the image cant be downloaded seperatly, as its a generated image
Are you sure about that? Once it's generated, it is still fed to your browser and thus, downloaded from the server to your client machine. What does the image's source attribute look like in the html? Something like <img src="CreateImage.asp?someP
Try using this method and passing it the full URL as indicated by the image's source:
http://vbnet.mvps.org/inde
If caching is an issue, try this alternative:

Thanks for all your help guys. I found a solution to the problem, I'm just going to take an image of the entire webpage and cut out the image i need. I found this example on the net:
