Rails - Aug 2005 - how to display both a generated image and its image map

Using XML RPC, I am fetching a generated chart (PNG) and its image  
map from a PHP server.   The question is, now how do I display both  
the chart (base 64 data) and the image map (HTML)?   If I make the  
action display the chart with "send_data", then the image map HTML  
gets lost.   If I insert the image map HTML into the corresponding  
view, then the chart gets lost.

The only options I could think of were:
1. stick the chart in the session;  have the view make a call to a  
second rails action in which the chart is pulled from the session and  
displayed with send_data
2. write the chart to a file with a unique name somewhere in the  
document root;  insert an <img> tag in the view that references this  
chart

I didn''t like either solution: #1 seemed messy to maintain if I am  
displaying a lot of charts.   #2 seemed messy having a lot of temp  
files lying around; it also potentially exposes private data to other  
users.

Has anyone needed to do anything like this and have a better suggestion?

thanks,
Jeff

I don''t remember off-hand where I saw that, but there is a way to
encode
the image data in the img tag somehow.  Search the web, or maybe someone 
will remember how to do that.

If I remember correctly that was to be used in E-Mail, to prevent having 
to download offline content.
