Click 'Browse'.
Click 'Upload' after selecting a photo.

After choosing the picture I would like to post, I get returned to the screen that tells me to choose a file, should it tell me why my file did not upload? If not, what is.the max file size?

Picture Size:
Mark's quote on picture file size:
"When it comes to uploading images to a Mingle2 account, the actual file
size is almost unlimited. The number of pixels in the image, however,
is limited to 10 million. In other words, the product of width*length
must not exceed 10000000.

Pictures should be in .gif, .jpg, or .bmp format."
