Hi,

I have page\_attachments installed and running on Radiant edge. I also  
have MiniMagick installed. gem list shows:

mini\_magick (1.2.0)  
Manipulate images with minimal use of memory.

The \<r:attachment:image /\> tag works very well!

But in the Available Tags list, I can’t see anything related to  
generating a thumbnail. Is there something like  
\<r:attachment:thumbnail /\> ?

Thank you.

J.

In order to generate a thumbnail with MiniMagick, you need to set the  
processor to :mini\_magick. You can do this in the PageAttachments  
model, just where it says “has\_attachment”.

I have written my own tags that allow you to access the thumbnails,  
but these are currently not in page\_attachments. It is a very easy  
tag to add, you just have to understand how attachment\_fu works.  
There is a good tutorial on attachment\_fu at [http://clarkware.com/cgi/](http://clarkware.com/cgi/)  
blosxom/2007/02/24#FileUploadFu, which shows all the various parameters.

There’s no specific support for thumbnails, other than being generated  
to support the UI. They are 50x50 by default. Would a “thumbnail” tag  
be helpful?

I solved it by writing an image tag with a “size” attribute. This  
just passes a key to the public\_filename in attachment\_fu. Then I can  
make and access any size I want using something like  
\<r:attachment:image size=“thumbnail” /\> with calls the image path  
with “public\_filename(:thumbnail)”. This gives me a great deal of  
flexibility to autogenerate specific sizes and easily call them.

Awesome, Keith. I’ll put that in the extension right away.

I forgot, I did something similar on the link tag, so that you can  
make links to specific image sizes as well. I don’t use this one  
much, but it is good for embedding light box images in blog posts and  
such. Like this: /[http://bitchkittyracing.com/articles/keiths-visit-](http://bitchkittyracing.com/articles/keiths-visit-)
