Lulu One-Piece Cover Uploader Question
I've just recieved my Lulu book (my trial copy) but its cover is completely off. I've gone back into my image file and checked the resolution, and I've made it to their exact criteria (3767px by 2775px). Logging back into the website, I notice that the cover previewer shows a green border around the entire image with scissor icons, and that this border seems to line up exactly where my cover was clipped upon arrival.
Does anyone out there know what I'm doing wrong? Why would Lulu ask for a specific image size for the cover just to trim it during conversion? If anyone has a workaround or solution to this problem, or knows exactly how many pixels Lulu clips during this process, I'd greatly apprecite it, as I'm quite annoyed and would love to have the cover I've worked so hard to format and create print to the specification Lulu needs without their extra "trimming."
