UPDATE: Since Twitter has now ditched RSS feeds as part of their careful plan to make using their service increasingly difficult for anybody that doesn’t want to use their clients, Twimage no longer works. At all. Sorry!
Twimage is a PHP script I wrote that grabs your Twitter account’s RSS feed, reads it, strips it down, and then prints the latest tweet from it to a 648 x 40 pixel PNG image. You can then display this image anywhere you would normally be able to put a regular PNG image file – including your forum signature! The final result looks a lot like this (resized for width, see full size here):
Because Twitter’s RSS feeds are painfully unstable – often returning HTTP 400 errors for no fucking reason whatsoever – I’ve also included a Twimage Feedchecker. This is nothing more than a simple PHP file which tries to print your RSS feed in plaintext, and will helpfully tell you any errors it encounters so you can accurately troubleshoot. I’ve also included the source file for the background image, if the colours I’ve chosen don’t take your fancy.
I’m not going to lie: this script is basically a complete and total hackjob and is very, very rudimentary in nature. RSS2HTML does most of the heavy lifting, and I just polish it, clean it up and print it into a PNG. It’s nothing that somebody else couldn’t write for themselves in about ten seconds, and indeed if anybody out there wishes to improve on it (which shouldn’t be hard!) I welcome them. I’d love to see what you do with it. Enjoy.
