Just think a little:
Where is the image stored?
How does it get into the browser?
And how can an application interfere with the above process?

Solution 1

Here is one suggestion (using a webbrowser control)
http://www.vb-helper.com/howto_net_grab_web_images.html[^]

Here is another solution that can use the mouse to define which bit of the screen you want to capture TeboScreen: Basic C# Screen Capture Application[^] (It's in C# but there are plenty of free converters out there)

or

Given a URL go get the image and download it http://forums.asp.net/t/631768.aspx?Downloading+and+saving+an+image+from+URL+using+VB+Net[^]

That's not quite the same as the original question! You would be better off blocking the site or preventing images from being downloaded to your browser - there are products out there. Or write your own browser.

How can I preventing images from being downloaded to my browser

CHill60 7-May-14 4:52am

This Wikipedia page http://en.wikipedia.org/wiki/Help:Options_to_hide_an_image[^] includes instructions on configuring various browsers to prevent images being displayed

Ayman Khoshouey 7-May-14 4:59am

I want to do this programmically to prevent just the unsiutable pictures not all pictures.
I have Matrixs for all skin colored and I want to change the RGB of the pixels of the porno pictures to be Dark color letus say "bm.SetPixel(x, y, Color.FromArgb(132, 15, 151))"

CHill60 7-May-14 5:08am

Then I guess you will have to write your own browser that does that before you render each image - see Bernhard Hiller's earlier comment

Ayman Khoshouey 7-May-14 5:14am

That means there is no way to do this with the common browsers?????

Ayman Khoshouey 7-May-14 5:10am

this is the code I used:
Dim bm As Bitmap = New Bitmap("C:\trash\Babymono100.bmp")'100 x 100 pixels picture

Dim x

Dim y
i = 1
PictureBox1.Image = bm
For y = 0 To bm.Height - 1
Me.Show()
For x = 0 To bm.Width - 1

Dim c As Color = bm.GetPixel(x, y)

For i = 1 To 255

If CInt(c.R) = CInt(DataGridViewSource.Rows(i).Cells(1).Value) Then
bm.SetPixel(x, y, Color.FromArgb(232, 123, 100))

Exit For
End If

Next
Next
Next

Fine ... now how do you propose to get that into the browser?

Ayman Khoshouey 7-May-14 5:16am

I have a problem that the PictureBox give nothing......I can't access the DataGridView and get the compare between the color

CHill60 7-May-14 5:19am

Getting back to your original post - you can't get this code into the browser so you are not going to be able to obscure the images.
This is a completely different question about *how* to obscure an image

How can I catch the image from the opened website and modify it using VB.net

My questions had two part the second part is how to modify the image.
Is there a method to do this with the common browsers???

CHill60 7-May-14 8:34am

AFAIK there is no way to do that within the common browsers.
If you want to do something yourself try looking for image overlay processing e.g. http://www.techrepublic.com/article/watermark-your-images-with-this-vbnet-code/#.[^]
or Merging Images in .NET[^]
