I don't know whether the small grid you mentioned is a pixel or a grid It may be the pixels of the bitmap. The appearance of the grid indicates that the pixels of your picture are low, which is due to the settings when the picture is taken.In the other case, each phase element is directly visible after more than 200%, and the larger the single phase element is, of course, this grid will appear.Digital photos cannot be magnified indefinitely.(Even film amplification is limited) If grid: view display pixel grid can be removed
Just create a layer of the size you need Then drag the photos you want to put together Ctrl+T to adjust the size and direction of the photos, and finally save as OL
I think you want to merge. First, you need to create a new CTRL+N, and then drag the pictures to be merged to the new document with the mobile tool. CTRL+T changes the size and adjusts them to be satisfactory!wish you success!
