Right, I’m not actually using the WP Portfolio plug-in. I’m using a theme that makes use of portfolios and am having an issue where any action that involves the theme altering an image (re-sizing, thumbnails, etc) cause the image to be broken. The images themselves appear just fine.
I’m posting here because I’ve been through the ringer the last 3 days trying to find a solution, with theme support, trial and error and scouring the internet…to no avail. Raweiss’ problem sounds exactly like what I’m encountering.
