I am using a handler to pull an image from the database and I need to resize the image while maintaining the aspect ratio.I have seen a few examples, but they were all pulling the image from the filesystem and not a database. This is the code I am using inside the handler to pull the image from the database:

Can someone point me in the right direction?

In 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.

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.

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 images at the head of the page in an iframe and in the main center page. The image at the head flows over the social icons and the images at the center page resizing drops below and pushes the other image down. I just want the images to resize when the browser is being resized. Go to [URL] .... and you'll see what I mean.

I'm using the slideshow extender, however the images are not a standard size. The images are user supplied, and they are often displayed full size, so I can't standardize them. I need a way to resize them on the fly, and have them look good.
I've been working on this slide show off and on for some time. I've had many false starts, finding out after putting in quite a bit of time and work that there is just one thing or another that I cant't get to work. I'm hoping this ajax extender will be the answer. It won't be if I can't rezise the images.
what the extender can use as image sources? I know it can use an image on the hard drive, which is where my images are, but then I have the size problem. I tried using a webpage that uses a third party control to resizde the image, but that didn't work. I'm looking at this site: [URL] for resizing the images, can the output be used by the extender?

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)
