Now there are a lot of things that make a photo good, but here are some basic things to keep in mind.

Make sure you upload a high quality image.

Make sure you're the only person in the photo and make sure that you're dressed appropriately for your field.

Basically, make sure you're wearing what you would wear to a job interview that could obviously vary from field to field, so just make sure it looks appropriate for you to add or change your profile photo.

Go to your profile page and then click the photo.

You can then upload a photo from your computer when you're done to save and that's it.

Your profile photos uploaded, and you can change or edit it at any time.
