Hi,
I’m facing a similar problem: I can create a gallery, and upload the images (and I can access the actual uploaded image in the directory), in wp-admin I can see the images thumbnails and so on, just like it’s suposed to be, but in the store the images are not displayed as thumbnails or in lightbox, and if I purchase the image, the link provided gives me a blank page.
I think there is some problem with image.php (look at my problem description in other ticket: http://xparkmedia.com/support/topic/image-php-not-displaying-images/), maybe related to permissions, because after I upload the images, I can’t change the permissions by ftp, I’ve followed Shu instructions, but it’s not working either.
Do you have some clue to try?
Thank you very much!
