since optiPNG and jpglib are both command line tools, you can use them within your ASP.net project easily without using powershell scripts.

There's an example for executing command line tools via ASP.net at www.willasrari.com/.../000155.aspx

Thanks omar for your quick reply from your busy schedule. I am new to powershell and i tried to do what you asked for but it gave me some errors as follows:

cmdlet foreach at command pipeline position 2

Supply values for the following parameters:

Process[0]:<$filename = $_.FullName; cmd /c "C:\soft\png\optipng.exe -o7 '"$fileName'"">

I dont know what it wants to say i have already copied the optiping.exe to the specified folder and i am running this command from my website root, do i have to run it from my App_Themes images folder or what i cant figure it out.Please Help.

Thankx

Aashish

Install powershell and run powershell

Go to you website folder within powershell console

Run the scripts

It will compress all the pictures inside your website folder

Now you can copy those compressed files to your production environment.

Can you please tell me the procedure to use these scripts in my website project. Do i have to make a separate deployment project to run those scripts or i have to place this code inside a batch file. i am simply not getting the way to do this.Please help me to handle this.

Otherwise your post sounds really interesting and is going to save a lot of bandwidth.

Thanks in advance for help and support and good work out their to help everyone.
