Create beautiful Facebook cover with 2-7 images literally in a minute. Beside actions which are automating process there are and 28 Layer Styles with photo-graphic effects plus 30 beautiful patterns which you can use for background. Beauty with patterns is that you can preview images with all patterns in 60 seconds, no need to place them one by one, just click next pattern in Fill dialog.
Actions to create Facebook covers with 2-7 images comes with two different border effects: stroke outside of image and torn edges. Using provided Layer Styles you can easily change default white border color to black and to add vignette effect or even to give them beautiful frames with single click.
Note: to use faster method where you can select all images from once you must have Load Files into Stack script installed which is part of Photoshop CC and prior Extended versions. If you do not see this script in File > Scripts menu, no worries, there is separate folder in package with exact same actions and exact same capabilities which are using Place command available in every of previous versions (I am recommending this files for CS4+).
