View 1 Repliesi have to modify the thumbnail width and height as well as main center image and height. then the thumbnail list displays images with a small portion of mail image.i want to display thw hole image with reduced size inside the thumbnails.
View 2 RepliesIn my Web page,I have a Div section with height=302PX and width=302PX.
In another page,I had a File Upload control. When we will upload the image,then the image will be displayed in that Div section.
1.When the image is large,it should be re-size and display in that particular Div section completely.
For Eg:The image size like 350PX*350PX and 1024PX*1024PX, it should be re-size to Div Section size has 302PX*302PX.
2.When the image is Small,it shouldn't be re-size and display in that particular Div section completely.
For Eg:The image size like 50PX*50PX,100PX*100PX and 302PX*302PX ,it shouldn't be re-size and display in that Div section.
For Eg:The image size like 15PX*15PX these will appear very small.But When uploading the file these images also should displayed completely with as it is in that Div section.But the image will displayed neatly.
3.If there are any tools for these type of conditions using ASP.Net.

View 1 RepliesLet's say I am creating a image hosting website. My potential users will be somewhere around 1 Million, and every user potential has 10,000 images, and I need to serve over 1000 images per second.
So, I bought a diskarray, with 10T storage, SAS 15K SCSI drives.
The problem is: What is the best way to save those files on disk? How to organize the folder structure to make sure NTFS can find one file from a billion files under a huge tree folder quickly? I mean, serve 1000 images per second is non trivial issue. My current website is serving over 100 images per second, and I already see the performance problem: NTFS can't find the file fast enough! And of course, my folder structure is not good enough either.
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.

View 4 RepliesI'm building a website for a friend where some pictures need to be uploaded. The pictures need to get a watermark on them automatically after uploading (to prevent other people using them as their own), but the watermark placement cannot be 'static'; if I put it in the same place on each picture then it will obscure too much of the content in some pictures.
So I want to enable my friend to choose the location of the watermark (possibly even the size, but that's not really important at the moment) for each picture individually.
At the moment I just have a page with a FileUpload control that allows my friend to pick the image. It is uploaded when the OK button is pressed and the URL to the image is stored in a database. That's basically it.
Now I was thinking to make another page after the upload page where you can see the image you just uploaded and can drag a picture of the watermark (which will be a transparent PNG image, possibly GIF if PNG is not possible) around to place it. Once placed, the user could click an OK button and the watermark is copied onto the image.
So what I need is a way to drag an image (the watermark) over another image (the picture), as well as the possibility to retrieve the location of the watermark image (relative to the picture image) afterwards (so I can draw it onto the picture using GDI+).
Is there anything that allows me to do this? When I search for stuff related to dragging images all I find is drag and drop samples, where you take an arbitrary image file and drag it into the browser. That's not what I want; the watermark is always going to be the same image, and it will be on the image by default (in the center or something). The user should be able to move it (possibly outside the boundary of the image to completely hide it) but never completely remove it from the image and drag it somewhere else (no drag drop).

I have a regular asyncfileupload that I use to upload a particular image from my hard drive to the server.
Since I'm testing it, instead of saving the image to my hard drive and then uploading it to my server using the fileupload, I was wondering if I can somehow save it directly from the image's url to the server.
I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel:
[Code]....
in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!
I have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.
I am trying to put a default image in an Image control in asp.net and it should show that particular image on the page when no other image is assigned or no image available in Database.
