hi and thank you for responding. I believe my images are all correctly-sized because it’s just the mugs that are showing up this way. I will have to check to make sure that the image for the mug that I am selecting is the correct one, although I do believe it is and printful just seems to want to use as a default the sideways picture of the mug; and then I do have to go into Shopify to edit it and have the main picture be the front view of the mug, which changes it on the printful dashboard; but not when you try to click on my shop in Instagram, the old default picture that Printful loves so much of the sideways view of the mug shows up, so I’m thinking that the problem is with the Instagram integration of Shopify? Printful didn’t seem to offer any explanation, so I’m just trying to see if anybody here knows how to fix it.
