[Plugin: Twitter Hash Tag Shortcode] One glitch and a lost Option

The Glitch
The profile image is only working if I do this conditional:
if ( isset($image) )
instead of the original, wich has a wrong var name:
if ( $images )

. . .
The Lost Option
This call only makes sense if there were an option being set somewhere
get_option('twitter_hash_tag_cache');

A transient would be the best, no?
