I had a play today and put together this mod to downsize images uploaded whilst posting a topic or uploaded via FileManager.

Resize Images on upload
Mod Version: 0.9
WWF Version: 9.63
Mod Download: http://www.LureLovers.com/WWF_Mods/Functions_Upload.zip" rel="nofollow - Download Zipped Functions_Upload.asp Here
Mod Author: TonyM
Release Date: 12th Nov 2009
Updated: N/A

Installation:
Download and extract the Functions_Upload.asp file to the Functions subdirectory of your forum (Backup/Rename the old file first so you can revert to it later if you wish)

That's it!

Alternatively edit the file yourself using the code example below

Requirements:
ASPupload and ASPjPeg need to be installed on your WebServer (they are installed by default on Web Wizing)

Overview:

Basically if an image is larger than 640 pixels in width I resize it to 640 and maintain the current aspect ratio. All tested files uploaded end up significantly smaller (including those smaller than 640px wide) which is great for saving space and bandwidth.

I also changed the max image upload in forum settings to 2mb as the files are resized upon upload, although you can obviously set that to whatever you like.

In \functions\functions_upload.asp
after this code (approx line 170)

               
                'Get the file name
                strNewFileName = .Files(1).ExtractFileName]

I inserted this code


                If strUploadType = "image" Then
                    'Dimension variables
                    Dim Jpeg

                    ' Create instance of AspJpeg
                    Set Jpeg = Server.CreateObject("Persits.Jpeg")

                    'maintain aspect ratio
                    Jpeg.PreserveAspectRatio = True
                    
                    ' Open source image
                    Jpeg.Open .Files(1).path 

                    'shrink if it's greater than 640px wide so it fits nicely on pages
                    If Jpeg.OriginalWidth > 640 Then
                        Jpeg.Width = 640
                    End If    
                        
                    ' Save resized image to disk
                    Jpeg.Save .Files(1).path
                End If

I hope it's of use to someone, I noticed a few other people were asking for this when I was looking to see if it had been done to save me doing it!

If you use it please let me know how you go!

Cheers,

Tony

TonyM: Is it possible to make a version af resizing code, so it works with these Components:
AspUpload3.0.0.3
AspSmartUpload 3.x
AspImage 2.x
W3 Jmail4.4
MyODBC-3.51.12
ODBC.NET

Because these is the only components ive got on my webhost.

I think you will find that the components are within your requirements madpakke, but always make a backup first of any files you intend to change

Actually, TWS, thats incorrect.

ASPupload and ASPjPeg need to be installed on your WebServer (they are installed by default on Web Wizing)

Madpakke listed the components his server has, and it did not include ASPJpeg.

ASPUpload will only upload the image (hence the name) it will not resize it, you need an Image Editing component for that (ie ASPJpeg).

Most of the ones he listed are irrelevant, but the one hes looking for is ASPImage, to replace ASPJpeg. The problem is, the code that TonyM has written will only work with ASPJpeg, so Madpakke is asking for it to be altered to work with ASPImage.

Hi Madpakke,

I'm more than happy to have a look at it when I've got a bit of spare time.

I'm not familiar with ASPimage although I had a quick look at the link Scotty32 kindly provided and it looks like it will have the functionality required.

Cheers,

Tony

2 or 3 questions on this script (great idea, by the way)

1. Can I assume that since we host with Bruce and company here, this will work with our forum?

2. I see I can edit the number so if we wish, say, 800 instead of 640 that's pretty simple, however, what about those who upload files to use in their SIGNATURE......... is it possible to let 640 be the default, but choose a smaller size for signature photos, etc.? Or is that a non-issue?

I can't recall which upload process is used, but Bruce is the host, his package, server, etc so I believe it's got everything needed..........

Tonym>>> Do you got a test forum where we can see the resizeing script in action.?

This is a really great MOD that makes life so much easier for our image "challenged" uploaders. Works like a treat and keeps my users happy (and me, not having to deal with resizing requests) ...

@ billd3
1 - Yes
2 - If images uploaded have a width less than the value you have set in the script they are not resized.

@ madpakke - No I do not have a public test server (only my private offline one) I use this script on my own live forum at www.lurelovers.com

@ pbanks - Thanks, I have a few "image challenged" users on my own forum, and this has saved me a huge amount of time (plus encouraged members to participate who otherwise would not have) Thumbs Up

I downloaded the file, compared it to the file we have been using, the ONLY difference was the resize part.
So I simply uploaded the file as it sits, no mods.
I then tried an image that was known to bee too large....
Instead of an upload and resize, I got an error stating the image was too large..... it is 400K and we're limited to 200K.
So sort of defeats the purpose, eh? The image has to be already small enough in order for it to work, OR did I miss something??

G'Day Bill

This would be the bit that you missed Wink

"I also changed the max image upload in forum settings to 2mb as the files are resized upon upload, although you can obviously set that to whatever you like."

OK, Tony, here in the states, we have the expression "DUH"
I think it's appropriate that I use that now.........
DUH! Of course, that rule would block any upload before the script could work.
I'll give that a shot.
Being that new cameras often create files that are 2.5 meg in size or so (at least mine does) I'll have to raise it a bit.
Thanks ;-)

This is SOOO cool!

If you want to get even smaller image sizes, just ad the quality-parameter from 0-100, where 100 is the best quality. I recommend 75:


'maintain aspect ratio
Jpeg.PreserveAspectRatio = True 
Jpeg.Quality = 75

If you want to resize. you should to ensure image isn't break.
I'm prevent image file size 18-20kb
If the user's avatar is too large you can use div tag to contain it.
