Facebook prevents uploading images that are 160x160; the pictures must be uploaded at 180x180. Facebook then scales the picture down to 160x160 automatically. I would like to achieve a pixel-perfect alignment between the Facebook timeline cover image and the Facebook avatar but the scaling causes alignment issues. I cannot find exact steps that:
- Are updated for the recent dimension changes.
- Provide a template suitable for GIMP.
- Walk through the Facebook picture upload process.
- Describe how to crop the avatar to align with the cover.
When uploading the avatar to Facebook there is a crop tool but it doesn't show how many pixels are being cropped. It also doesn't say the size of the cropped image. This makes it difficult to determine whether Facebook will still scale the image down, or exactly what transformation will be made upon the image.
What are the exact steps (explained with screenshots would be great) to upload (1) a cover (at 851x315); and (2) an avatar (at requisite dimensions) such that the images are perfectly blended?
