An image/image hosting question for the world

[huinare]

For the first time in over ten years, I've been inclined to share artwork with The Internet. Once upon a time I was adept at such things, but in that decade+ I have not kept up with the shifting knowledge required to competently deal with the programs involved. I'm progressing in that I found a place to scan the project in question, rather than taking a cheap photo of it with my mobile yet again.

But THIS ONE THING IS MYSTIFYING. When open for editing in either Gimp or MSPaint, the image is 1600x640 when viewed at 100%. It is another, smaller size in the 'windows picture & fax viewer.' I figured, okay, the latter program is being a simpleton--but, it also uploaded to Photobucket in the same smaller size, about 1000x450.
Yet when I right-click on the image file to get its properties, it -does- say it's the first and larger size, 1600x640.

WHY?

This is stupidly obvious - but are you absolutely certain you've only got one copy of the file and are looking at the stats for the same file every time?

Other than that I have no idea! If it was just photobucket, I'd wonder if the uploader was set to do some resizing at the same time, but if windows thinks the file is that size to start with, that seems unlikely...

Yep!

Well with Windows, the odd thing is that when I click on the file's properties it says clearly that it's the larger size, yet the default windows viewer displays it at the same smaller size that Photobucket thinks it is.

I'm wondering if it has something to do with some weird compensatory adjustment somewhere, given that my computer screen is so tiny. Maybe something thinks I don't have any business viewing a 1600-pixel-wide image. o_o
