Thank you for the response. Automatically save default color I can't? For example I'm using images in my blog http://www.3dteach.info and I'm red arrows. Change the color of each time a little stretches.
How automatically to save in jpeg? Now when I push button to save me the format of png is offered, and I want that it was offered to me saved in jpeg. Constantly to choose from the list of jpeg uncomfortably.
