Getting creative with your Facebook cover photo for your Timeline can be difficult. What size do you make it? How can you incorporate your profile picture into the cover? You see all of these creative covers on other profiles, and want to follow suit.

So, where do you begin? Well, you can begin with our guide to customizing your cover photo. If, after reading that post over, you're still looking for a simpler way to create your cover photo, look no further than your iPhone.

As Mashable reported earlier this week, Facebook Cover Designer (available from iTunes) aims to help you make the best Facebook cover photo you can. The app itself is free, with an in-app upgrade of 99 cents available that unlocks some extra features. Here's a quick rundown of how the app works.

You can either take a photo directly in the app, or you can import a photo from your camera roll, Facebook, Picasa, Flickr, Photobucket, or Instagram.

Once you have selected a photo you can crop and adjust the photo. You can select whether you want the profile picture to be included in your creation, or if you want to simply create a cover.

If you opt for the former, you will need to fork over a dollar to upgrade to the Pro version of the app. Doing so will also unlock some "Pro" filters for you to apply to the photo before you upload it.

After cropping and adjusting the photo, you can apply a filter to the photo.

Once you are happy with your photo, you can upload it to Facebook. You will see a progress bar as the app uploads your cover, as well as profile picture.

In my experience with the app, uploading a photo (either a standalone cover, or cover with profile picture included) did not change my cover and profile picture on Facebook itself--it only uploaded them. I then had to log in to my Facebook account and manually change my cover and profile picture to the uploaded photo or photos.
