I've got WP 3.6.1 and wp-cycle 0.1.13 on a 64-bit linux (Ubuntu 12.04.3 LTS). Today I uploaded a couple of images to wp-cycle. The images appeared to upload correctly, but they don't show in the slideshow.
I'm guessing the images were too large to display properly. This would be OK, as I can easily scale the images, but there now seems to be a hiatus in the slideshow at the end of the cycle, i.e., as if wp-cycle is showing a couple of blank images. (There is a blank display for about three of the usual cycle times after the last picture in the show has displayed and before the show cycles back to the first picture.)
Is there some way to confirm/deny that wp-cycle is "displaying" the blank images? And, if it, is there a way to remove the images? They don't appear on the usual wp-cycle Settings page, so I can't delete them in the usual way.
