how can i change property of a photo? I tried to work on JPEG photo to change its property?

Do you have a Photoshop Edition !

Then you can add the image to Photoshop and then save it as your desire format or you can send me the image and I will make it for you :)

Sir, can you be more specific on which properties you want to change? If it's the author, title, description etc properties, then follow these steps:

right click on file >> properties >> Summary Tab

right click on file >> properties >> summary tab >> advanced (right side bottom, if advanced changes are to be applied)

If you want to change the pixels, color etc, then follow these steps:

Open your image in either paint shop from below steps:

1) Start >> All Programs >> Accessories >> Paint

Under paint, File >> Open >> select the file that you want to modify and then make changes

Alternatively,

Right click on the file that needs modification, select open file using the following program and under the list of programmes, select microsoft office picture manager and make changes.

If these aren't the two things you are looking for, please give additional details.
