Just to clarify the situation BR549 this thread was made for the old site.
To upload a picture to the New AFN is much easier than before.
You can either to choose to use the "Upload File" (bottom left of the screen) or drag and drop a picture.
Picture file size matters, if you file size is too large it won't upload, I think max file siz3 is something like 5Mb.
Either make sure you camera resolution is set on a low level or you can use a program to reduce the size of your file by compressing it.
Some programs have an icon to optimize the picture for websites etc.
Great you found a work around.
