Dynamically Image Resize From Web Directory And Display It - Not Thumbnail
Jun 23, 2010
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.
I 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

After saving image in db how can we retrieve it in gridview like thumbnail size image and by clicking on image in gridview its open as preview. How can we do this in asp.net using c#.
I have googled around for a solution and it seems that a lot of posts are dealing with these kind of things. Unfortunatley none of them seem to help me. I'm trying to resize an image dynamically to create a thumbnail. I'm basically loading a current JPEG into an image object and using the following commands to create a new image:
[Code]....
I put the image which I get from the code next to a manual re-size which was made in Photoshop. You cannot even compare between the two, the dynamic one looks so blurry when you compare it to the one made in Photoshop. Is there a way around this? I imagine Microsoft found a solution for this by now. Otherwise I will have to upload manually 4-5 different versions to every image on my website which doesn't sound right to me.
How it is possible to dynamically resize an image using an image handler nd web.config file?like i want each image uploaded by user to be resized to a specific size(aspect ratio) before being upload to server from database i also want that the resized image must not loose its Aspect ratio.
display images in small size (thumnails) and also resize the image size (kb) so the page will quickly upload images. i dont want the user will upload 2 version of images (large and small) and i dont want also to resize the image size while uploading the images to server. I want the user will upload the original images (320x480 px) and when the users will watch the gallery they will see small images (120x180px) with small kb size that will uploads fast.
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:
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.
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?
However, if there is not an image - e.g. if my property record doesn't have any images associated with it, I would like to display a default thumbnail.
So I could create different folders according to the page unique id. I have also created a thumbnail image from the image I have upload (cropped ones).
The problem I am trying to figure out is to display these images as a slide show from these dynamically created folder (display thumbnail in the page and clicking the thumbnail need to see the full size image just like slideshow).
I was trying to see examples in jQuery but its just client side. So is there any way to load these images and display as a slide show from the directory. Should I deal with DirectoryInfo in C#? Expecting a simple one.
I'm trying to create a list of image buttons dynamically, but I'm having trouble displaying the images. I'm using the Directory.GetFullPath method, but I don't think its the right thing to do.I've viewed the page, and the image path is showing as
'd:Hosting6238630htmlPropertiesCedarsext%20front.jpg'. I know this isn'r right and that it needs to be something like www.annereevelettings.co.uk/property/images..., but the question is, how do I do it?The page can be seen at the following address
I have a Folder which consists of number of images. Initially have to load the first image from that folder in a page. when user click the first image it should display the second image where it will have next link for the third image. when the user click the next link now then it should display third image where it will have next link for fourth image and previous link for third image where it should repeat upto the end of the image.
Can any one tell me how can i display images one by one by passing query string value to the images and how to change the link dynamically for the images
Update:
Intially i want to load the first file without passing query string, with the first file there should have next file link. Once the next link button is clicked then only have to pass the query string.
how to pass the query string from second file to end of the file,
DirectoryInfo oImageFolderInfo = new DirectoryInfo(this.ImagePath); FileInfo[] oFileList = oImageFolderInfo.GetFiles("*.*"); string fileName=string.Empty; if (Request.QueryString["filename"] != null)
I found this code on another site and it works great for resizing the image and keeping the quality. What I want to do at the end is check the height of the image and if it exceeds a certain number, just change the size of the image. Not resize it but just cut off part of the bottom to be a certain size.
Code: Dim image As System.Drawing.Image = System.Drawing.Image.FromFile(src) Dim srcWidth As Integer = image.Width Dim srcHeight As Integer = image.Height Dim thumbHeight As Integer = (srcHeight / srcWidth) * thumbWidth Dim bmp As New Drawing.Bitmap(thumbWidth, thumbHeight)
i am using file upload control for uploading images. in that iam checking the condition,if Image.Width > 250 || Image.Height > 400 then i am resizing the image. but it is giving the error "The SaveAs method is configured to require a rooted path, and the path 'ProductImages/roman_sandals.jpg' is not rooted."
ProductImages is folder where i am saving image. Can anyone find why this is giving error,my code is
