Running Printify into TikTok Shop. A large chunk of my catalog sits at POOR listing quality, and when I pull the diagnosis API the complaint is always the same one: MAIN_IMG_INVALID "Use real images of the product and not illustrations" Some things I have confirmed, in case it saves anyone time: - It only ever flags the first image. Nine images in the gallery, and slots 2 through 9 have never once been flagged. - TikTok's own "suggested images" fix is useless. It returns 7 or 8 suggestions that are all the same photo at different crops and resolutions. Applying them swaps one image for a re-crop of itself, and the tier never moves. I have applied it on several listings with zero change. - Swapping to a different on-model Printify mockup did not help either. Same result, still POOR. What I am starting to suspect is that it is not judging the photo at all, it is judging the artwork printed on the shirt. My text-based designs mostly pass. My illustration-heavy designs fail almost across the board. One of my brands is text humor and passes most listings. The other is illustrated animal art and has never had a single listing pass, using the exact same mockups. Questions for anyone doing Printify into TikTok Shop: 1. Do you get MAIN_IMG_INVALID, and are your designs illustration heavy or text heavy? 2. Does anyone use the Standard Printify plain product-only or flat swatch mockups as the main image instead of the lifestyle on-model ones, and did that clear it? 3. Has anyone actually moved a listing from POOR to GOOD, and what specifically did it? Thanks all, -Elie
