but the problem here is that as i am able to retrieve data IMAGE_CONTENT,LOGO,CONTENT,POS,ALPHA in a single query] from database but i dont know that how to use this detail and where to use these details in my WATERMARK class...
How can i do that with ASP?
Is this process going to be a great overload for the server?
Could i use an image for a watermark instead of simple text?
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.

View 1 RepliesIs there a way to upload image and save to folder with watermark of Copyright on image ?
View 1 RepliesIs 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 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:

internet Explorer cannot display the webpage when trying to upload a large image.I have a webform for inserting images. There are four FileUpload controls on the page, allowing the user to upload 4 images at the same time. It inserts them directly into database, in Image field, but before that I am resizing them to 200px x 160 px.
The problem I am having is as follows: If I try to upload larger images (over 2MB), one at the time, everything goes fine. But if I try to upload 2 or more larger images at the same time, I get the message: Internet Explorer cannot display the webpage, and there is a button below: Diagnose Connection Problems.
Can you please point me to what could be an issue? It obviously has something to do with the image size, but I have no idea what.

I have tested my pages in Firefox & IE and looking at Firebug in Firefox for some reason some images are taking a long time to load. They are not very big in comparison to the ones which are loading quicker.
Attached is a screenshot of Firebug.
I especially notice it in IE with the progress bar at the bottom of the page, it just sits there saying loading image...
Could it be the path or something which is http://localhost:49211/Content/_layout/images/bg-footer.png for example

i posted a problem few days ago
i was trying to upload images
after using the upload asp control
i save them into an array to upload them all at once this is working fine on the localhost but if the array contains more than 3 images on a different PC on the domain it gives me an exception
the exception "Cannot access a closed file"
i am saving my images in a folder in the same project and only the path in data base i do not know if that the best solution but i considered the performance that way will be better
i tried the solution mzmishra gave me
< httpRuntime maxRequestLength="10240" requestLengthDiskThreshold="4096"/ >
it did work and there is no more exceptions in different permition levels but in a permition level the images does not saved in the server so when i tried to view them there is no image to view.
Is it possible to edit images using a javascript library and then send the edited image to the server for saving.
Edits will be in real time, means the user can see the edit result in the same time he is editing without the need to refresh the page.
I want a javascript library to do some edits on an image on a webpage 'such as crop, resize, rotate,...' and send send the edited result to the server.
