VS 2008 - Image Format To Save With Smaller File Size After Uploading With Website?
Aug 11, 2011
I have written a website and let the user upload their photo. It also resizes the picture to 400 x 400 and crops automatically to the center part of the picture. All of this works good but each file is about 355K each for JPG and PNG file formats. I just tried GIF and it is 49K but the picture is grainy when saved this way. Is there any way I can get the picture to a smaller file size with keeping it at 400 x 400? I really thought PNG would be the way to go and was surprised by it being the same as jpg. I don't want to lower the quality either for JPG files.
Users of my C# web application can upload images. I have configured the max upload size in the web.config file to maxRequestLength="1024" and executionTimeout="180".
How can I check the upload size before uploading? (do you have examlpe or url?) Another option might be to check the dimensions?...
Some web application allow the user to crop the image at client side. Do you have an example of this or url?
I 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 am working on an ecommerce application, user will be uploading several images of a product, instead of stripping the size (i.e the KB or MB size) after uploading it on the server, i want to strip the size of image before uploading it to the server ( bringing the size from any thing over 30KB down to 30KB) i.e on the client machine itself and then upload it to the server. i understand that this requires a download on the client machine which makes me ask the following questions :
a. can i use a java control in dotnet since java control can be used on all OSes b. is there any dotnet control that might be userfriendly to all OSes
I have a database that I just migrated data to. It has grown to 769MB from 13MB when I shrink it, it does not get any smaller. I don't think the amount of data should have made it grow that much. Could I be doing something wrong?
With the ajax file uploader, would it be possible to check the size of the image before uploading?Currently, it uploads the file to the server and then lets me know that it's bigger than the limit size.
I have figured out that javascript cannot obtain the filesize of a to-be-uploaded file because it is a security risk and it is not allowed access to the clients HD. But I want to see if it is possible to get the file size before uploading the file, perhaps using AJAX.
So by looking at the requests, when you click the submit button on a form that contains a input type=file, the Request actually has the filesize inside of it, so you could therefore get the first request, cancel the request there, and send the file-size data back to the client without actually uploading the file.
I want to do this via AJAX so that it doesn't post back and also without clicking the submit button. It seems impossible to create a submit request with javascript because there is no way to get the file size. But is there a way to fake a submit? How does the submit button get the information? Is there any documentation on how the submit button actually works?

I need to upload images from client to server as follows:
1. Server is passing the client a file name 2. Client is checking file extensins to ensure it's an image then issues a __dopostback to the server. 3. Server uses the FileUpload control to save the image on the server.
I have that all covered, but, if image is too large, the upload fails with the following error: 'System.Web.HttpException: Maximum request length exceeded.'
Is there a way to check file size on the client (without the use of ActievX which also errors out), before it is passed back to the server?
currently we are configured execution Timeout="1200" (The default is 110 seconds) and maxRequestLength="12288" (The default is 4096 KB)but some times users upload files above 12MB so we are getting "Maximum request length exceeded" error.we are checking the file size using client side javascript ActiveXObject object. but ActiveXObject only works in IE not in others like mozilla,crome,..Jacescript Code are
[Code]....

have a working ASP.NET 3.5 webservice that accepts standard POST requests using an encoding type of application/x-www-form-urlencoded. I then added a method which needs to accept an uploaded file. We change the encoding type of the request to multipart/form-data so that we can get the file data and now we receive the following error:System.InvalidOperationException: Request format is invalid: multipart/form-data

Can anyone one give me a link to a tutorial or step by step guide on how to do it? I'm not even sure what data type to set the attribute to in the database.
