I have stored images in folder each images is more than 700kb so datalist binding process became slow.so it is possible that while loading record and corresponding images from folders Can I reduce the image size or compress images so that record fetching become faster.In database i m stroing image path and image is stored in directory.
View 1 RepliesI am using a sql server 2008 database and I am uploading images to the server using an asp.net webapplication. I have an image column that I use to store the images. I have chosen the database to store the image and not a folder on the server, because the database table will contain only very few rows. maybe close to 10 or 15 rows.
My question is, Do I have to reduce the size (dimensions and quality affecting size on disc in kbs) of the image in code behind before uploading it to the database or do I keep it as is. The total upload size permitted is 200kb. I am thinking that when the image size (size in kbs) is small my webapplication performance will not be affected when displaying them from the database.
I have uploaded a .jpg image and resized as Small and Large thumbnail. The small image is (135 X 173) but after resizing the small thumbnail image file size is of 40.8 KB. And mostly all images (around 64) thumbnails having file size more than 40 KB. Due to which thumbnails taking lot of time to get display.
Is there a way through which we can reduce the image file size upto 8 to 12 kb, but without effecting image quaity??
Below is the source code that i am using for resizing an image:
If FileUpload1.HasFile Then
Dim stream As Stream = FileUpload1.PostedFile.InputStream
Dim x As String = IO.Path.GetExtension(FileUpload1.FileName).ToLower
If x = ".jpg" Or x = ".jpeg" Then
Dim image As New Bitmap(stream)

when I load the web page the image's file size stays the same rather then reduce.

In my web application, I have used AJAX Toolkit and my .net version is 3.5. When I run the application and save the page, so many ScriptResource.axd and WebResource.axd generate which makes the file size 200 to 300 KB more big. After doing the same procedures mentioned in the above link, it was working fine as all ScriptResource.axd and WebResource.axd file is removed.
But when I go from one page to another page using on click, then Object Expected Error comes and when I debug it,I found one ScriptResource.axd file containing query string like .axd?d=-bA.like this and Request. GetResponse cannot find the file and it gives 404 errror (File Not Found).
I have the line where is goes "Hide Suggested budget with tolerance %' then the box is too large. It is almost fine, you can see here

The box holding the '5' for the Tolerance percent is too large. How can I reduce this?
the code for all this area is here:

Given a URL to an image (and not the image itself), what's the most efficient of getting it's dimensions? I would like to change the height and width attributes in the image tag (<img>) if it is greater than 200x200. However, if it's smaller than that, then I'd like to keep the size as it is. (I'm using ASP.NET/C#)

We need through command line to build our site (which we already do using msbuild.exe), but the resulting files are way too many and it takes our to ftp it to the server. I am able to publish the website and reduce its size by ~90%; however, we need to do this through command line not manually using the GUI. I have read many postings but noone is clear on how to do it (and msbuild seems to no be able to do this). Can anyone provide me a link. We are using Visual Studio 2010 and DOT NET4.0
View 3 Repliesm using asp.net 3.5 and c# on my website.Here is myquestion:I have an upload button and asp:Image on a page. An user can upload an image from his computer and that image will be displayed in the asp:image. But before I display the image, I would like to check the width and height of the uploaded image. How do I do this?
View 3 RepliesIm getting some images from a webpage at a specified url, i want to get their heights and widths. I'm using something like this:
Stream str = null;
HttpWebRequest wReq = (HttpWebRequest)WebRequest.Create(ImageUrl);
HttpWebResponse wRes = (HttpWebResponse)(wReq).GetResponse();
str = wRes.GetResponseStream();
var imageOrig = System.Drawing.Image.FromStream(str);
int height = imageOrig.Height;
int width = imageOrig.Width;
My main concern with this is that that the image file may actually be very large,Is there anything I can do? ie specify to only get images if they are less than 1mb?or is there a better alternative approach to getting the dimension of an image from a webpage?
I have file upload UI element in which the user will upload images. Here I have to validate the height and width of the image in client side. Is it possible to find the size of the image having only the file path in JS?Note: If No, is there any other way to find the dimensions in Client side?
