Ok I agree,

But showpic.php no longer exists.

<IfModule mod_rewrite.c>
RewriteEngine On

# Prevent serving TYPO3 404 pages for missing files
RewriteRule
^(typo3(conf|temp)?|fileadmin|uploads|t3lib|clear.gif|index.php|favicon.ico)
- - [L]

# Do not rewrite static resources
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -l
RewriteRule .* - [L]

# Rewrite the rest to index.php
RewriteRule .* /index.php [L]
</IfModule>

Results on amount of mod_rewrite log lines for a page with normal
content and one missing image:

Current .htaccess rules untouched: 58 lines
New .htaccess rules untouched    : 85 lines
New .htaccess rules + Ernesto fix: 51 lines
