Google Image Search and Search Engine Friendly URLs

does google image search dislike index.php in image urls

[sublimespot]

It seems google handles search engine friendly urls pretty well now. Im talking about URLs such as:

[codes]
[site.comm...]
[/codes]

Ive set up a dynamic image system on my site which uses a similar technique. Google Image Search has not spidered any of these images yet. Here is the URL style in question:

[codes]
<img src=http://site.comm/image.php/0/big-green-monster.jpg">
[/codes]

Im curious if this is a problem or if I need to get rid of the .php extension in there so that it does not know that these images are dynamic?
