If it's less than two weeks since you uploaded them and your co-worker cannot easily see them - e.g. if they go to the cemetery page and it doesn't have a "Transcribe Now!" message like this:
... or if it does have this message, but they click on it and are told to come back in two weeks, then the system is working as it should.
There is meant to be a two-week period for you, the photographer, to fiddle with your images - to delete the ones you don't like, to link the images that are of the same grave, to transcribe the ones you want to do yourself, and so on - before they are unleashed to the public in the general transcription pool.
1. The two-week period sometimes fails. I have occasionally picked up images from the general transcription pool that were taken only the day before.
2. Even when the two-week period is working, there is a back door into the images. On the cemetery page, click on Images:
If there are any untranscribed images, by default these will be displayed first, and it will display them whether they are still in the two-week period or not. I don't know whether this is a bug or whether it's deliberate, but I've found I am consistently able to get at images within the two-week window by doing this.
It's very handy for when I've asked a photographer to take pictures of graves in a particular cemetery for me. As soon as they upload them, I can go to Images as described above, and find their pictures. So if your co-worker really wants to see your images and the two-week period still isn't up, tell him/her to give that a try.
3. There's another back door into the images. You will notice on the cemetery map that some of the grave pins are green:
The green ones are the untranscribed graves, and again, I've discovered that it doesn't matter whether the two week period is over or not - you can click on a green pin and see the picture no matter how recently it was uploaded. And again, I don't know whether that is a bug or whether it's deliberate.
