Web Forms :: Image Thumbnail Does Not Display
Mar 4, 2011
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.

I've got:
<asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl='<%# "PropertyDetails.aspx?propertyId=" & Eval("propertyId").tostring %>'><asp:Literal ID="Image1" runat="server" Text='<%# Eval("imageId", "<img src=""images/properties/{0}_thumb") %>' /><asp:Literal ID="Image2" runat="server" Text='<%# Eval("imageFormat", "{0}"" alt="""">") %>' /></asp:hyperlink>
which displays an image from my db.
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.

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 am using asp.net ,C# what is the best way to achieve this?

A user will upload the images through FTP in the images folder. So my requirement is when he clicks on the link say for eg [URL] all the images should be displayed in the thumbnail format. What I did is I opened the IIS and over there I selected the directory listing. So when I click on the link [URL] it shows the list of images. But I want this in the thumbnail format.

I have a gridview which displays thumbnails in the first column and details in the other columns. The thumbnail URL is being retrieved using the following:
[Code]....
However, if the thumbnail cannot be located, a white box with a cross appears instead (as expected).
To handle this better, I would like to display a different image if the thumbnail cannot be located for any reason, for example an image saying "Image Cannot Be Displayed". But I am unsure of how to do this, of even where to do this. Essentially I need to assess the value that the datagrid is using for the particular URL when it is databound. But can I put VB.NET code in this?

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

I am creating a website where users can upload a profile picture. When a photo is uploaded I am resizing it and generating two new files one for a thumbnail view and one for a large view. Both photos are stored in the same folder and the file names are stored in to two different columns in an SQL table against the users membership account. The two new files use the following naming convention:
Random_name_small.jpg
Random_name_large.jpg
I am then using a grid view with a custom template and an image button to display the Random_name_small.jpg. What I would like to do is when some clicks on this thumbnail photo to then display the associated Random_name_large.jpg. From the SQL select command I am reading both the Random_name_small.jpg and Random_name_large.jpg and then binding Random_name_small.jpg to the image button. Can this be done using the details view or should I be rewriting the code manually to display these images.
