Why can't I upload a picture to use on my yahoo profiles?

I play yahoo fantasy sports. I'm trying to upload a picture to use on my team profile. I have been able to upload pictures before, but I can't this time. From my profile page, I click on "Change Image." Then I click on "Add Photo." Then I click on the "Browse" button and select the image from my computer. Then I click on the "Upload" button. Then I crop the image to my liking and then click on the "Crop" button. Then, when it asks me to select an image to use on my profile, that image is not there. I've been trying to do this several times.

I've tried several different jpg images, all within the size requirements, but without success.

If it didn't meet the format and size requirements, it would not allow me to proceed at all. Does anyone know why the image doesn't actually show up after I upload it and crop it?

Thank you.
