It won't let me post the same pic twice, it only needs to be slightly different I guess but still it's extra work. If we post a monster card, then we have to make it unique for next time and it's a PITA because it lowers the quality every time it's recompressed etc.

The error is:

>R9K prevented at least one of your files from being posted.

>as i understand, r9k is a per-board configuration that the BO can enable/disable maybe it's enabled there

>It's labeled "Unique Posts" in the board settings page.
