Question How to find the image size in Kb?

[saichong]

hi all

i want to know how to find the image size in kb if the image is from a web site?

is that possible without loading it??

You can look at the ContentLength property which will be in bytes. Dividing by 1024 will get you the kb value you're looking for.

Here's an example using the logo from the boards here.

		Dim req As HttpWebRequest = CType(WebRequest.Create("http://www.vbdotnetforums.com/images/vbdn/MainLogo.gif"), HttpWebRequest)
		req.Credentials = CredentialCache.DefaultCredentials
		Dim resp As HttpWebResponse = CType(req.GetResponse(), HttpWebResponse)
		Dim imgSize As Int64 = resp.ContentLength
		MessageBox.Show((imgSize / 1024).ToString())

Error 1 Type 'HttpWebRequest' is not defined.
Error 2 Name 'CredentialCache' is not declared.
Error 3 Type 'HttpWebResponse' is not defined.
