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

Rails is entirely indifferent to whatever you put into the ''image_tag'' because all it really does is create the normal <img src=""> html tag and then it''s up to the server to deliver the file and the web browser to parse it and display it. Also - FTR - when you say ''adding a root password in database.yml'' that immediately makes me nervous because root should never be the user of any sql database - at least in my opinion.

The browser handles the displaying of images when a page is rendered. Thus, any of the above mentioned formats should work. However, you need to make sure that you''re referencing images correctly within your page. -Conrad> 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.

Hi Craig, Thanks for your advice.> Rails is entirely indifferent to whatever you put into the ''image_tag''That''s what I expected. Asking about it is like taking a Flu shot: it wards off possible ills.> root should never be the user of any sql database ...I agree, with the exception of my machine that is: - protected from the Net and malware - I am the sole user - and it''s only for development purposes BTW, that''s how the author posted the code.

Hi Conrad, Thanks for your response.> PNG, JPEG, and GIF has nothing really to do with Rails.Great! I couldn''t how enacting my plan could run afoul of Rails. But there''s always the possibility that I overlooked something. So I sought advice from more experience Rails people.> you need to make sure that you''re referencing images correctly within your page.I got that covered in this case; I''m paralleling a working app. Best wishes, Richard On Feb 26, 7:49 pm, Conrad Taylor <conra...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> On Fri, Feb 26, 2010 at 4:30 PM, RichardOnRails < > > > > RichardDummyMailbox58...-gP6xRNRnnqSxhq/XJNNIW0EOCMrvLtNR@public.gmane.org> wrote: > > Hi ALL, > > > I''m building a Rails app using the app provided in Ruby On Rails > > Cookbook.
