If you're trying to do a regular expression based search and replace,
you probably ought to use preg_replace instead of str_replace, as
str_replace doesn't parse regular expressions.
Try this one out, I think I got what you wanted to do:
<?php
$file = "screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg";
echo preg_replace('#(screens/)temp/(.+?)_1(_main\.jpg)#', '$1$2$3', $file);
