I’'m using Spark 1.0.2 which I understand just started fully support .PNG files as avatars. I was previously using a .gif file and had no problem. But now there are a few users using .png files, and every day when our spark client logs in, our avatars are missing and we have to go back into our profiles and add them.
I’‘m converting the .png files to .gif to see if that takes care of the problem, but I thought someone should know it was happening. I’'ll post the outcome after the change in filetype.
