We are not doing any server-side resizing of images, so this resizing
is definitely happening in the browser.
Now here's the difference between viewing from DOCS and from NAV: when
viewing from DOCS, you get the raw file (well, more or less, but for an
image, that's true). When viewing from NAV, we do need to bundle
navigation information into the output, so that Forward and Previous
as HTML when running Remote-less.
is where /adm/wrapper comes in - it uses frames to do this (unless you
are in accessibility (screen reader) mode, which I assume you aren't.
So I think what the browser does is adjust the image size of JPEGs to
windows, but not to frames.
Currently, I do not see how uppercase or lowercase .JPG could have an
impact, but I have been wrong before.
I would very much recommend *against* going in by hand and renaming the
files, especially since currently I do not see how the case of the
extension could make a difference. Just FYI, you would find the files
in /home/httpd/lonUsers/ndsu/(courseID)/userfiles/ - if you rename the
files, you also need to change the references in
whichever sequence the images are referenced from (do a "grep" on the
image filename on all *.sequence files in that userfiles folder), and
then make sure to re-initialize the course.
