Hmmm. I'll have to look at the code, but I think I can see where your screenshots would have been rejected.
The minimum size, for the fullsizeimg.jpg file is 1280x720 and the maximum is 1920x1080. 1280x1080 might actually fail if I goofed the logic. Entirely possible.
If the utility is dropping the name at a space, I did not know about it and will put that on the list to get fixed.
By the way, there is no negative intent in saying there is no screenshot available. I was obligated to say it or people would have been all over me about it. People have been asking for a long time for me to put up images of newly released skins so I finally got around to figuring out how I could do it.
Thanks for all the efforts on the new and updated skins. They are really looking sharp.
