Question about Photoshop

I made an image on Tuesday, I made the same image on Wednesday, but the images border was jagged (Wednesday) and the border was very smooth (Tuesday).

Any reason why?

The smooth border is attached

Perhaps the anti-aliasing in your text menu got changed? When you are using the text tool look up to the toolbar by the font size menu. There should be a menu with two A's next to it and it should have four choices (crisp, smooth, sharp and none I think). Try playing around with those settings and see if it helps.

That done the trick. Thanks
