If your images aren't appearing on the BYO Booth photo grid, you might need to make an adjustment to your settings in Twilio via their website.
Create a file called webhook.php on your webserver and enter the URL in Twilio's settings as shown below.
Place the following code in your webhook.php fie:
<? header('Content-Type: text/xml'); ?> <Response> </Response>
Be sure to put the webhook.php URL in this text box:
After you save these settings, restart BYO Booth and send a text to your Twilio number with an image. It should then appear.
