In the Image size window> Pixel Dimensions, I think I put 200 pixels, but don't remember if i made a change in the >(document size) which, I see the resolution box, and don't remember if i change it to Bicubic Sharper (best for reduction). I just follow a video tutorial.

In the resolution box do I have to change to a high number?

Thank you for your help,
I really want it to learn how to save it in the right way with the experts like you all are.
thank you again!
