These images will always appear on your timeline, and ideally they will show up in most of your followers’ News Feeds — though with the decrease in organic reach, it’s unlikely that everyone will see your post.

The more people engage with your post, the more likely it is that the rest of your followers and their followers will see that activity.

It’s quite a bit larger than your profile photo so make sure to save it at the highest resolution possible.

Uploaded photos will appear in your followers’ streams and the streams of their followers (if Retweeted).

It’s important to note that Twitter may collapse your photo into a smaller version to fit in a user’s stream.

Your profile picture will also appear when you post to other walls, comment on posts or when you’re searched with Facebook’s Open Graph (that’s a fancy term used for its search function).

Image Guidelines Your cover photo will only appear on your Facebook timeline, but it is a lot bigger than the profile picture, which gives you more freedom to choose something creative.

This image is going to be housed on your personal timeline, but it is going to take up a great deal more space than a shared link or image, so it’s a good place to celebrate the victories that keep you going!

Image Guidelines Facebook Events help capture the attention of users and cut through the noise on Facebook.

Make sure Twitter displays the portion of the photo you want followers to see by setting the width of your image to fit the minimum requirements.

Also, horizontally center your content to avoid odd cropping.

Image Guidelines Another great tool in your Facebook belt is the ability to share a link.

It’s very similar to posting a shared image, but it gives you even more fields to work with.

Say cheese: this is going to be the photo representing you or your brand on Facebook.
