I agree with everyone's points here, but if you really wanted to or had to, you could enable CLR integration on the SQL Server, create an assembly that could resize your image, and then call it from a trigger or proc. Its not very hard. Here a page that describes the process: http://msdn.microsoft.com/en-us/library/ms254498(VS.80).aspx

Basicly to enable CLR on the SQL Server:

sp_configure 'clr enabled', 1
GO
RECONFIGURE
GO

Create a c# assembly to resize your image:

using System;
using System.Data;
using Microsoft.SqlServer.Server;
using System.Data.SqlTypes;

public class ResizeImageProc
{
    [Microsoft.SqlServer.Server.SqlProcedure]
    public static void ResizeImage(int ImageID, int width, int height)
    {
       //TODO: ResizeImage Code
    }
}

Compile the assembly

csc /target:library ResizeImageProc.cs 

Load the assembly in the SQL Server:

CREATE ASSEMBLY ResizeImageAssembly from 'c:\ResizeImageProc.dll' WITH PERMISSION_SET = SAFE

Create the proc

CREATE PROCEDURE ResizeImage AS EXTERNAL NAME ResizeImageAssembly.ResizeImageProc.ResizeImage

After that you can call it like a normal proc. For example:

EXEC ResizeImage(1,800,600)
