Thubnail images should display with out any change in Quality i.e by DataList Control
On Click of Thubnail images Fullview of image with width and height same as image width and height

I have a ModalPopupExtender control inside accordin control, users can add images, that I sotre the path in database(sql server) and the actual image in physical address inside web server,I automatically resize the image to thumbnail size in C#, when users first connect to the site,the see the thubmnail version of the image,which is much faster to download,and by clicking the thubnail, the hidden asp:pnael is shown with imzge in full size, I use javascript to unhide the panel and also change the image source to actual image,everything works fine in IE, but in Firefox and Chrome, the first time user clicks on thumbnail can not see the full size image,only after couple of time, they see the full size image? what could be the problem?
I am using asp.net ,C# what is the best way to achieve this?

I am using C# language with asp.net
I have an Image control on my page that should display a thumbnail preview of the actual image. The URL property of this control is assigned through the code-behind using:
imgHolder.URL = @table.Row[0].ItemArray[0].ToString();
Before moving my files to another location, this assignment works fine (The files used to be located inside the application folder). But after moving all files to another drive in the same server, the images don't seem to render any longer. I can upload/download files fine but they just won't display as thumbnails on the page.
Does anyone know a free way of doing this in asp.net?
View 4 RepliesI have a working application to save an image file to my sql database (Saves as "Original_Image" in the DB TBL_ImageGallery). I have a file limit on the upload of 1 MB. This also works great and the image is being saved beautifully. I found a bit of an issue. Being i am working on a network with 2 bonded T1 connections the streaming of images to my site, when tested internally, is effortless. I am not sure that this will be the same with a generic bandwidth. I want to store the original image size into the databse (already done) but also store a smaller sized (in bytes not actual size [Width, Height]) to my database in a "ThumbNail" column. This will allow the browser to only have to pass the "Thumbnail" sized image, obviously this needs to be much smaller than the original (ex: 1MB orignal I want to save as 12KB image in the thumbnail column), to the thumbnail img control in the user's interface.
I am not sure if this is possible or if there is a need of third party controls. I am interested in doing this as either a stored procedure or in the C# code on an event fire. There may be a better / other solution to this and if that is the case I am also interested

i am facing a prblem about image resizing.. i know it is a common problem but the scinario is little different here. i have some image in my server image directory and also have their small 128 X 128 sized thumbnail..i show a page with those images like 'facebook photo album' and also linked another page to display them..when a picture is clicked it refferd to that page and that page loads the full sized original image along with picture comments bla bla..., the page width is fixed to 1024px, and the div's width is 800px max which contains the <asp:image..../>; that shows the full sized image. here the problem comes, when a original sized picture is greater that 800px then the remaining part of the picture is croped !! i know it will happen.. that is why i planned to show a thumbnail like pic which's size will be 800px max and link the page with a pop up java script page which will contain the full sized picture only. the problem is i can't resize the picture in a limit of 800px on fly.

Have a look at this link.Web pageIf I want to have this kind of speed in my page load which consists of many thumbnail images. It that image is stored in database or in file system.What measures to take to achive this kind of speed like indexing, denormalization, caching and what else?
