I’ve received a few comments and e-mails from people that dislike having Imageshack set as the default destination. The next version will not upload to Imageshack by default, instead it will either use the “File” option or “FTP” which will pop up a menu to set your FTP settings or optionally use “File” or “Imageshack” instead.
So for those of you that have not yet downloaded v188.8.131.52 (beta) it does indeed use Imageshack by default at the moment, but rest assured that it will be changed. If you want to change away from using Imageshack, you can do so by going to the “Main” tab and changing the Screenshot Destination to something else (File, FTP, Clipboard). Also you can change the destination by using the right click menu of the tray icon (”Send Image To”).
The reasoning behind setting the default to Imageshack was to beta test HTTP uploading.
