While Twitter’s longstanding 140-character limit is not changing, media attachments no longer count toward the limit. (https://www.theverge.com/2016/9/12/12891562/twitter-tweets-140-characters-expand-photos)
If you’re using the SNAP API, you’ll need to do the following to take advantage of this:
(1) In tw.api.php, change “if ($options[‘attchImg’]!=false && $img!=”) $twLim = 118; else $twLim = 140;” to “$twLim = 140;”
(2) In tw.php, change “if ($options[‘attchImg’]==’1′ && $imgData!=”) $twLim = 117; else $twLim = 140;” to “$twLim = 140;”
I imagine this will be changed in the next official update. But for now, enjoy!
