Recently, I saw the template Plantpic is usually used in userpages. However, I soon noticed that it needs a PNG image type, and changing the name (which usually works on many other sites) will only cause a MIME file type mismatch. This can be a big problem for many people, because usually, images are JPG.

But now, I've created a new template to use them in userpages with a JPG-compatible template: Template:ProfilePic! Using this is the same as the Plantpic one, but the images do not need to be PNG and have a "2" behind it's name. I hope this new template helps you!
