[Plugin: WP-Cycle] Error – Can't Upload Images

I followed the tutorial and added wp-cycyle.

I have the transition settings on and I have the width set at 600 x 400. The image I also uploaded was exactly 600×400 pixels.

When I add an image I get:

Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in /usr/blog/wp-content/plugins/wp-cycle/wp-cycle.php on line 117

Warning: unlink() [function.unlink]: No such file or directory in /usr/blog/wp-content/plugins/wp-cycle/wp-cycle.php on line 121

WP-Cycle Images
Sorry, but the file you uploaded does not seem to be a valid image. Please try again.

I’m basically using a vanilla agency template and this was the first plugin I messed with, it’s not interfering with others.

Any ideas?
