phpBB has pretty strict image limits: 90x90 pixels and <6kb. The easiest way to take an image you like an fit it within these requirements is to use Squoosh, which can both aggressively compress and resize the image.

It looks like this — and make sure to select "Advanced Settings" to reveal Resize.



And note that phpBB requires hosting images yourself and putting them behind a tag like this.

thank you!
