Hi leegclystvale,
I think you misunderstood me. When you view properties of a jpg file, there's a property name "program name" shows which program created the picture. In my situation, it's Photoshop. All I want is remove it.
Ahhhhhhhhhh, I see :o)
Try irfanview
Options > JPG Lossless Operations: Transformation None, Optimize, Save with Original Date/Time, and either Clean All APP markers, or Custom Keep Comment only
Or yu can do it in photoshop by saving for web but that will degrade the image. You need to keep an eye on the settings.
Try both and don't do it on the original if it's important :o)
