Myself, Carol & Maureen actually approve the images that are uploaded, so it depends on which one of us happens to be online and in the RIL at the time that you upload as to when they will appear. Actual human beings are behind the curtain! (like the Wizard...
I have to say though, that I don't see your images in the Approval queue right now.
When did you try to upload them? If it was about a month ago, there were some problems site-wide then with the Uploader, so some things didn't come through - but all seems to be working now.
If it was today, I haven't seen your images. Please do try again!
Are these the images you are talking about? or were there more?
