1. Picture frame style: Use the rectangle tool to draw a 2 10*270 pixel rectangle with the color #986830 and no border. Select "Silk Fold" in Texture, add the effect of "Bevel and Relief/Inner Bevel", and select "Fold" in the hypotenuse-shaped option bar. The effect is similar to a wooden photo frame. The height is 16, the depth is 100%, the edge ambiguity is 3 and the shadow angle is 135.

2. Save the style: click the graphic to execute "Window/Style" and click the "Save" button (+sign).

3. Draw a picture frame: Draw a white rectangle on the wooden picture frame, resize it, click the new style in the Styles panel, and immediately fill it with white. Select the wooden frame to add shadows and halo/projection effects.

4. Add a frame: Perform "File/Import" to import a picture, without occupying the whole white frame and aligning it with the center. Select a painting, execute "Bevel and Relief/Concave Relief", and then execute "Shadow and Halo/Inner Shadow" to add a concave effect to the frame.

5. Click on the white frame, the filling edge is "feathering" and the mixing method is "color multiplication", so that the white frame and the wooden frame are integrated.
