I am doing a project on digital watermarking. This is the process. The user will choose his image file to upload, chooses his image key(either from the visual studio gallery-folder name is Image Key, or he chooses his own from the directory).
He enters a password, and this password will be embedded into the image uploaded.
Next, there is an option to digitally watermark the image (This is where I am having problems - stuck with the codes)
Here is the work so far, and I couldn't get any further.
Is there a way to process images once uploaded to my asp.net site, to put a watermark or some text across the image to copyright the images? I would like to do this server-side if possible.The other option I have discovered here [URL] would be to store the images as they are on the server, but to manipulate the display so it appears the image is watermarked . However, this solution is in PHP. Does anyone know a good PHP to VB.NET translator?! Or does anyone have a good suggested link, idea or code? Or can I add PHP to my ASP.NET site?
I have a page that display like a print pre-view. It shows the watermark in the background. But when I print it, it doesn't include the watermark. I know in IE7 you can change your IE settings to make it print the water mark but in IE8 you can't do that. Is there another way to print my water mark out? Here's that part of the code:
i have a page where the image,logo,position and alpha details are shown in a gridview...and the page has a confirm button...once the user clicks on confirm button[then actual watermarking happens which gets stored in db] it navigates to another page where another gridview is present but it has an additional column [watermarked image] ...the only problem is that when i want to write code for watermarking in the watermark.aspx.cs page
I want to save water marked image to database.i have done watermarking,but save the image it does not save to database.

write this post in the wrong section, if I do please don't hessitate to tell me.Now to my problem. I've been searching the internet for a way to display my images from my server to my asp.net website.The way I have it in my server (local) is that I have stored all the links to the images in the server (The images are on some other websites).Now my question is:How can i display the images on my website in asp.net? Is it even possible to display the images through a link or do i have to store the whole image in my database?If someone has some tips or links to other websites that go through I am using C# if someone is wondering.

i am using oracle database. visual studio 2005,asp.net c#. i want to upload the images to oracle database. I need help for creating the Database table also (i know to create database table, but i don't know abt creating image table (blob or clob));
I need to take an uploaded image, resize it, and save it to the database. Simple enough, except I don't have access to save any temp files to the server. I'm taking the image, resizing it as a Bitmap, and need to save it to a database field as the original image type (JPG for example). How can I get the FileBytes() like this, so I can save it to the database?Before I was using ImageUpload.FileBytes() but now that I'm resizing I'm dealing with Images and Bitmaps instead of FileUploads and can't seem find anything that will give me the bytes.
