I am so frustrated. I am obviously doing something wrong. Try as I might I cannot create a single avatar that meets the constraints. I don't know what I am doing wrong, since I am usually quite good with photoshop. What is everyone's secret? I have played with the pixels and resolution and the physical size. OY!
I use iPhoto. So I don't know how helpful I can be, but basically I just use the export feature to export the picture, and I use the size constraints to make sure the exported picture does not exceed 80x80 pixels.
If you have a piece of software that will allow you to do that, you're in business!
Oh, and if you use a picture that is parked on a website somewhere, I think you can avoid the 80x80 constraint. I'm not absolutely sure about that, though.
Well, I was having problems with that too. I tried to load in a sm. picture I knew was smaller that 80x80. I got so flustered.
I ask Amy to help, she didn't have any problem at all. It just loaded fine for her.
i crop the photo in a square 4x4 usually at 150dpi
then i change the image size to whatever it needs to be ie: 80x80 - still keeping the 150dpi
then i use "save for web" and it makes it small enough to be within the constraints, but still keeps it clear.
