[Rails] Replacing an xxx.png with a xxx.jpg in public/images OK?

Hi ALL,

I'm building a Rails app using the app provided in Ruby On Rails
Cookbook. The book's app works "out of the box" after appropriate
tweaks: adding a "log" directory, adding a root password in
database.yml and a couple of rake executions ... which is more than I
can say for many books. (Just wanted to give it a plug.)

In public/images he's got a main_logo.png file which he references in
the <body> of application.html.erb in
ink_to image_tag('main_logo.png').

I've got a .jpg that I'd use in place of a .png because my JPEG loses
detail when I convert to PNG. I expect that JPEGs and GIFs and other
major graphic encodings should work just as well in Rails as PNGs. Is
that true?

I ask because despite the fact that I'm using a working Rails app as
guide, I'm confident I'll make some mistakes I'll have to debug. I'm
just trying in advance to avoid one here.

Thanks in advance,
Richard
