Osbes managed to sort that attachment bug out on our site.
-> new version added
0.9.9 (28.07.2011)- images are now saved as jpg instead of png -> reduced filesize by a factor 10
- removed a bug causing weird characters to show up in the previewtext
- added loads of debug messages and a debug mode
- removed beta status - slider is running on our live site now
Attachments are working fine for us now. Important point: Guests need to be able to see them, if they can't neither can the slider.
Reworked the FAQ.
Next version will be uploaded once we've upgraded our board to 4.1.5 (given the upgrade calls for slider changes).
