There must be some way that I photo that I placed into my gallery can be removed, but I have spent the last 30 minuters trying to figure out how to do it without success.
Help please!
If I go into my own gallery and click on a picture, I get this screen:

Note the "Delete this file" button highlighted by the red arrow. Clicking on it will ask if I am sure, and then it will be deleted.
Obviously I cannot delete images from someone else's gallery, and I suspect that if someone uploads an image to your gallery, then you may not be able to delete it either.
I see that Matthew's name is below your airplane pictures. It looks as though you put your photos in the temporary album in early April, and once he had created an album specially for you, he moved the airplane photos from the temporary album to your one.
You will probably have to ask Matthew to get rid of these ones.
