I am interested in uploading an image to a file field using httpwebrequest or similar however I am stuck on a few things. Would it be a matter of add the file field and the image I would like to upload as the value? I'm not looking for code, I would like to learn how this can be accomplished.

I am not using with cmdinsertattachment. I am using Html - Input(File) from the HTML toolbox. the ID of the input file is ID="upldimg". So how do I insert this into my table which is -
Column1 ID identity
Column2 Img image
Column 3 Description varchar(200).
The insert statement like -
INSERT into table1 (Img, Description) values (???, txtdescription.text)
Do I do upldimg.text in the insert statement?
this is the code i used from this site. everything works fine, but i need a little different code to upload image-here's the code -

I want to use the http:[url....API function to upload a picture onto ImageShack and then obtain the image_link. The only problem is, how do you place an image with its file name with the form-data along with the API key? This is what is stumping me in trying to implement the function.By the way, OpenDialog is already implemented to select the file to upload.
Update: I tried adapting the existing code to use the Unified API and it still does not work. If anyone knows what's wrong in the code, just make the modifications... Otherwise,
Imports System.Xml
Imports System.Xml.Serialization
Imports System.Xml.XPath[code]......
I have a field in a SQL Server 2005 DB of type 'image' that contains documents, mostly pdfs. When I view the field in the database, it looks as though the data is stored as a hex string. I have extensively googled and came up with the VB.net function below to convert the field to an actual file, but it only outputs a file containing the string of hex characters rather than the file that the field is supposed to represent.
This is a sample of the fields' data (I have truncated it for privacy purposes):

I have always used the API for Vb.net from Decaptcher.com and have always sent the Captcha by sending an actual url to them as you see in the code below.

I want to be able to kinda like have a timer that will get an image off my Hard Drive, and upload it online, so that all I'd have to do is download the image, even if it's been written over, I want to be able to broadcast an image from my hard drive, using only my IP Address.
127.0.0.1 is my IP Address.8888 is the port.Somthing like if you were to goto http://127.0.0.1:8888/update.html or Update.Jpg If YOU were to go to this address on your machine, you could see the image... Of coarse, it will probably be an image of which I was able to get from Printing my Screen image, and then saving it as like C:Test.Jpg, but the Timer would get my Desktop Image, or Print My Screen and Save it and Overwrite the Test.jpg image on the C Drive... Ya know what I'm talking about?

I want to resize the resolution of an image before uploading it to local storage. Right now it saves the image in its full resolution and I have to manually resize it using width="200" height="200" or a css tag in aspx. I want to reduce the file size of an image before storing it, hence by resizing the image resolution when the user uploads it via button. I've tried using System.Drawing before and setting the int imageHeight and int maxWidth to be resized but couldn't seem to get it to work.
My code so far is:
Protected Sub btn_SavePic_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn_SavePic.Click

I'm writing it again, i'm developing an app in which user click a picture through image and image will be stored in sdcard then I have choose the picture from image view and send that picture to the server. I have convert my image into the byte array and then encoded it in Base64 string format but when i try to send that image to the server it give me an error of soap fault. Here's the my code of android device:
public void doneImage(){
ByteArrayOutputStream out = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 100, out);

I am attempting to create a class library that can either search a bitmap to determine whether or not it contains an exact match to a second bitmap or if it contains a partial match. Currently it only returns true if i search the image for itself or if the sensitivity is below around 15%, even when i search with an image that i know should return true. The images I am using are simply a screenshot saved in paint and a section of that first screenshot also saved in paint. Here is my current .dll coding for VB 2008 Express

I'd like to use the webrequest webresponse method to test for the existence of a file.If the first file is there, then I want to test for the existance of the same filename with -1.htm appended to it. If that filename exists, then test for filname-2.htm This continues until the filename being tested comes back 404 error. At which point, the program does NOT blow up, but the do until loop stops and the code continues. I have to search for a link on each one of the pages found once I have determined how many pages there are.How do I test for a file and not have it blow up? It has to loop and it goes through at least once. this is code I wrote. Right now the page just keeps going and going. IE's little logo on the page tab keep going around in a circle like it's in an endless loop.

What can I do to fix this? Is it the good way to handle file uploads?
i have made a program that takes info from your registry and uploads it so I can fix it and you can download the new version of a key that makes things work faster.... when someone uploads a file, it works good, and i can look at the ftp's text file and see it, but every time someone ELSE uploads something, it overwrites the previous text file and makes another one, which deletes the first one. i would like so that when another person uploads something, it will just be on the second line then third, so on so forth.
