Stylize edges of an image

There are a few different ways.  One is to use the Roughen filter ( start with a line and apply the Roughen filter, may take some experimentation to achieve what you want ).  You could also build a mask with the two vertical ines roughened and the two horizontal lines straight ( join four separate elements to create a rectangle > then create a mask ).  If your background is a color, just match the color in the lines' stroke in step one above.

Place your image.

Click Mask.

Select a stroke weight/color.

Select Effects > Path > Outline Stroke

Apply Effect > Distort & Transform > Roughen.

Change the stroke color to the background color if nessecary.
