OK, here's how it's done in
v4.1.x ...
1) Add a new product text field called 'artist'...
Patch the database...
Code:
ALTER TABLE `xcart_products` ADD `artist` TEXT NOT NULL ;
2) include/product_modify.php
Look for...

Code:
$query_data = array( ... );
Along similar lines add...
Code:
"artist" => $artist,
3) skin1/main/product_details.tpl
Add this code in a suitable place...
Code:
<tr>
{if $geid ne ''}<td width="15" class="TableSubHead"><input type="checkbox" value="Y" name="fields[artist]" /></td>{/if}
<td class="FormButton" nowrap="nowrap">Artist</td>
<td class="ProductDetails"><input type="text" name="artist" size="18" value="{if $product.productid eq ""}{else}{$product.artist}{/if}" /></td>
</tr>
Or for predefined options...
Code:
<tr>
{if $geid ne ''}<td width="15" class="TableSubHead"><input type="checkbox" value="Y" name="fields[artist]" /></td>{/if}
<td class="FormButton" nowrap="nowrap">Artist</td>
<td class="ProductDetails">
<select name="artist">
<option value=""{if $product.artist eq ""} selected{/if}>None</option>
<option value="Van Gogh"{if $product.artist eq "Van Gogh"} selected{/if}>Van Gogh</option>
<option value="Picasso"{if $product.artist eq "Picasso"} selected{/if}>Picasso</option>
</select>
</td>
</tr>
