I am having the same issue with pictures. Did you figure out how to fix it?
I PM'd with Troy. He has been trying to rebuild a bunch of plug ins that were causing problems with the WKC app. Like I know what a plug in is. I played along though (lol). I think he fixed that but in turn it has caused other problems with WKC pics. He is trying to fix things as fast as he can.
That being said, I found I can resize my photos myself using Microsoft Paint. By reducing the pixels from 4800 to 1000, WKC then accepted my photos to upload. I used the "Help and Support" tab on my PC to find out how to resize my photos. I create a copy of the photo I want to resize so I am not changing the quality of my original photo. Once the resized copy is upload to WKC pics, I delete the copy. Few more steps but I was going through withdrawals not being able to post photos.
