I'm using the work-a-holic theme from graph paper press and i'm experiencing an error when trying to upload portrait images. File sizes are fairly small, they vary between 40kb - 150kb. I've been digging around for days trying to fix this.
The error i receive is:
Warning: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions in /wp-includes/media.php on line 1006
Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /wp-includes/media.php on line 424
Warning: imagejpeg(): supplied argument is not a valid Image resource in /wp-includes/media.php on line 455
I've tried a fresh install of WordPress and the theme and database - with no luck.
I followed the install instructions for the theme and thought leaving the image height blank could be the issue, but adding a value here doesn't help resolve this.
Any help you can offer would be great.
