Regular expression help with image extensions

[chas]

(! preg_match( "/^<img src/i", $show ) )

hi there i need to select all images with extension .png|.jpg|.gif

How do i alter the above RE to exclude images?

[Master_script_maker]

preg_match( "/^<img src=(.*)(.png|.jpg|.gif)/i", $show )

[chas]

thanks but shouldnt i break the dots for the extensions?

[Master_script_maker]

if you mean escape, then yes.here it is escaped

preg_match( "/^<img src=(.*)(\.png|\.jpg|\.gif)/i", $show )

[chas]

preg_match( "/\.(png|jpg|gif)/i", $show )

would this work???

1. i just need to detect the extension without the src part

2. and would it be faster to have the dot outside the extention part??

thanks again
