Ruby Forum Radiant CMS > conditional display of image

Hi,

I'm attaching some images to some posts on my blog, and as I don't want 
to
have too big images on the home page and on the archive pages, I devised 
the
following code that I put on the first part of my page

<r:unless cond="!request.nil? && Regexp.new(tag.locals.page.slug) =~
request.env['REQUEST_URI']">
!{float:right}<r:attachment_url transform="120" id="10"/>(foo)!
</r:unless>
<r:if cond="!request.nil? && Regexp.new(tag.locals.page.slug) =~
request.env['REQUEST_URI']">
!{float:right}<r:attachment_url transform="200" id="10"/>(foo)!
</r:if>

(the 120 and 200 transforms resize to 120x120 and 200x200)

The strange thing, it that I don't always get a "request" object, and 
I'm
wondering if there could be a better way to do that, the main point 
being "is
the page being displayed is the page I belong too".

Regards,

   Sorry, i don't quite understand the question.  The code you post, is 
in a
page, snippet or layout?

The code I post is in a page part.
I'm wondering if I could do something like tags.locals.page.id == 
self.id.
And after a few though, I could/should maybe make two parts, one that 
would
show on the page and one that would show in the Archive index.

Hum, maybe I should show what I mean :
http://w.mat.cc/
and
http://w.mat.cc/articles/2007/10/06/a-vif-une-touche-d-humanite/

That is, having a smaller image on the home page so that it does not 
take too
much room.

You should get the request object from tags.globals.page, not
tag.locals.page.

Is that "transform" something custom or does it ship with the Page 
Attachments plugin?

I see that in the "available tags for page" help, it says:

> <r:attachment:image />
> Renders an image tag for the attachment (assuming it’s an image). 
> The ‘name’ attribute is required on this tag or the parent tag. 
> Any other attributes will be added as HTML attributes to the rendered tag. 
> The optional ‘size’ attribute allows you to show the icon size of the image.

Also, are there other sizes available like "large" and "medium", or is 
"icon" the only one?

I think you used to have to change a couple of files.

In vendor/page_attachments/app/models/page_attachment.rb you can add
more thumbnail sizes:
:thumbnails => {:icon => '50x50>', :small => '160x160>', :medium =>
'320x320>', :large => '640x640>'},

and also change the admin view to find the right icon thumbnail:
<%= link_to image_tag(attachment.thumbnails.find(:first, :conditions
=> "thumbnail = 'icon'").public_filename, :class => "thumbnail") %>

Specifying a image size seems to expose the size="icon" attribute in
the outputted page though. Is there a patch out there for fixing this?

Just had a chance to try this. It works brilliantly! In the page admin, 
I can simply drag the link from "Attachments" section and add the size I 
want to the end of the file name. Ex:

http://domain.com/image_small.jpg

Since I use Textile, I then add the image tag (!) and float it right 
like so:

!>http://domain.com/image_small.jpg!

Thanks for your help, Dominic!
