I am quite an amateur when it comes to resizing digital photos, so I need some help please. I just hit my 500 post count and I am now able to add an avatar. I wanted to use a photo from my iPhoto library, but the photo seems to big for what is allowed by this site for an avatar. I tried Exporting the photo and using various settings in iPhoto to make the photo smaller, but I keep getting "file upload failed", so I am guessing that it is not within the specified size for avatars. What is the easiest way to change the size of photos so that I can use them, not just on this website, but also the many other sites that require certain sizes for avatar uploading? Thank you in advance.
