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#)

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?

View 8 RepliesI recently purchased a new domain for the sole purpose of hosting all the static content on a separate server and delegate CPU intensive operation like thumbnail creation on a different pool. Now I would like to do some operations on images uploaded to that remote server : creating thumbnails or updating the image if we need to. Should I download the images to my server, modify them there and then upload them back to the remote server or should I try to create web-services to manipulate the images?One of my solution was to provide an interface to upload and manipulate the images in the new domain, by leaving the old domain when it comes time to work on images, but I find it kind of awkward.I would like to keep the new domain cookie free. How would that affect my ability to restrict any random user to use the web-services if I decide to go that way?

I have a form that will accept and save a MP4 video file. I need to be able to get the dimensions of the video as well. This will be running on a server running ASP.NET 2.0 so any external libs must be able to be placed in the Bin folder as they can not be installed on the server.
how to get the information? If the same lib would let me transcode the video to flv that would be a huge bonus.
Update: The server is XP Service Pack 2 with .NET Framework (2,0,50727,0)
I'm taking input from a user and need to stick it into an array, the problem is, I don't know ahead of time how many dimensions the array will have and I also don't know how many items the user will want to stick in each dimension.The array will have a maximum number of dimensions of 4, but an unlimited number of items per dimension.I'm trying to create an unordered html list creator, so I need to know the number of items in each level of the list, and since (As far as I know) you can't create a multi dimensional array with a dynamic size
