So this is the bassic html w/ eRB:

![]()

But what if the database has a pic2\_url and a pic3\_url (some will have  
1 picture, some 2, and some 3)?

Obviously it shouldn’t display pic2\_url and pic3\_url if they aren’t  
there.

And what about formatting: I’ve got a 400x400 box set for pictures –  
if I have one picture, I’ll have it take up the whole table (supposing  
all pictures are at least 400x400); if I have two, I’ll have it put  
the pictures side by side (maybe breaking the table); if I have three,  
I’ll split the table again. (and no pic\_url at all leaves me with a  
400px box that I might as well remove.) How do I solve this  
problem?

Of course, I could just point to three “Image unavailable” images.

Thanks,  
JD

\<% if product.pic2\_url %\>  
 ![]()  
\<% end %\>

perhaps better to model the product pictures as a list instead of  
hard-coding in the assumption that there will be at most 3 though. then  
your erb code may become:

\<% product.pic\_urls.each do |url| %\>  
 ![]()  
\<% end %\>
