Thanks! Unfortunately I can's see the code you posted, although it's obvious there was no resizing.
I will have another look at the Admin settings, to make sure there's no resizing switch set. I could not find one the last time I looked, but...I got a little sidetracked.
Here is the image for the first image in the 10/24 thread:

I just used it on one of the other sites & it posted its actual size as opposed to shrinking it as it did here...
I guess you'll be able to see the code...which I think will include resizing...
