I know I know, before I even get started most of you are thinking this is pretty beginner stuff.
But it’s good to refresh every once in a while. Here’s how I do it:
<img src="profile-photo.jpg" alt="profile" onerror="this.src='default.jpg'" />
The important part is the “onerror=” that basically says if we get an error instead of the photo, change the image src to “default.jpg”.
There you have it! Quick and easy.
