Having Trouble Uploading Images to my profile...

Hello I've been having trouble uploading images. I last logged onto GiantBomb 12 years ago when the site first launched and decided to come back and get a little more involved with gaming forums since I'm looking to purchase a PS5. Anyways, any suggestions on what I might be doing wrong? These are 1MB jpeg files...trying to upload them from my desktop (Mac).

Are you seeing a specific error when you try to upload an image? What precisely is happening that prevents it from uploading?
