I have very basic knowledge of ASP.net. I am using following script to resize and image, but the problem is it increases the disk volume of resized image to almost 4 times or original image.
Example:
Original Image: 1024 x 769px and Disk space: 135 KB
Resized Image: 600 x 380px and Disk space: 825KB
Notice resized image becomes 825KB.

I have a file name that is either 5464821561564.jpg or 5464821561564R.jpg. If the file has a R at the end of it means it was resized but the orignal is still there. How can i take a file name see if there is a R on it then remove the R so i have orignal file and delete it? So in other words if a file has a letter R on it. It was resized need to delete orignal.

View 1 RepliesI have a program that gets data from an SQL database via some comboboxes. When the user has selected what they are looking for, I want to have a "preview" button which will generate the image (I've written this code already) and display it in a small, resized popup window.
A) I'm pretty new to this ASP, but know VB pretty well.
B) I have no idea how to make a new popup come up
C) How can I have the code written for the image generation point to that popup window? Also, I'm storing the image in memory. As this will have serveral users at once, it probably isn't a good idea to be saving this down. Here is the code for the file generation.
preview.aspx.vb
(There is no code in the aspx file, this is all in the codebehind file. Most of this isn't useful except for the end when I save the image as a stream - I'm trying to figure out how to link this stream to a new resized popup window.)

I am trying to save some resized images to the server. Why I get the following error on the vSmlImgFle.Save(vTmpDir.ToString & vFile.Name, ImageFormat.Jpeg) (in red below) line?
A generic error occurred in GDI+.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.
And while we are on the subject of dealing with image files, is there a way to get the file format from the original file, rather than looking at the file extension to determine the file type:
If Ext = "JPG" then
Type = ImageFormat.Jpeg
Else if Ext = "JPG" then
Etc.
I thought that vImgFormat = vOrgImgFle.RawFormat might do it but that seems to return something completely different than ImageFormat.Jpeg.
Code:
Protected Function CopyScaleImages(ByVal FileSet As FileInfo())
Dim vTmpDir As New DirectoryInfo(Server.MapPath("~/SanInspPhotosTemp/"))
Dim vDir As New DirectoryInfo(Server.MapPath("~/SanInspPhotos/"))
Dim imgHght As Integer

I am having weird display issues using the jQuery dialog with an iframe in Firefox and IE8.
I have tested the page itself outside of the iframe and the problems are not reproduced, only when inside of the jQuery dialog.
Issue,image actual size: 300x225 image display size: 400x300
JS Code - Parent Page
$(document).ready(function() {
var img = $('.photoLink');
var imgSrc = img.attr('src'); [code]....
The class of the image is set dynamically based on image dimensions.
The image path is set in the code behind, no styling or resizing done.
The images are resized upon upload to be no larger than 300x300.
Display is correct in Chrome and Safari, but in IE and FF for some reason it enlarges the image.

i need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup

View 1 RepliesLet's say I am creating a image hosting website. My potential users will be somewhere around 1 Million, and every user potential has 10,000 images, and I need to serve over 1000 images per second.
So, I bought a diskarray, with 10T storage, SAS 15K SCSI drives.
The problem is: What is the best way to save those files on disk? How to organize the folder structure to make sure NTFS can find one file from a billion files under a huge tree folder quickly? I mean, serve 1000 images per second is non trivial issue. My current website is serving over 100 images per second, and I already see the performance problem: NTFS can't find the file fast enough! And of course, my folder structure is not good enough either.
