Can I use a photo on a t-shirt/mug/tote bag?
Yes, for example, you can include a photo in a greater t-shirt design, as long as the end result of that design is significantly different than the photo you originally purchased. You may employ various methods and skills to create a significantly different design, including adding textures, adding unique hand lettering or illustrations, using Lightroom presets, adding graphics, using various Photoshop add-ons, etc. However, you are not permitted to purchase a photo and put that photo on a t-shirt unchanged.
End Products must be significantly different than the original Item and require time, effort, and skill to produce. End Products must not be used or sold in a way that is directly competitive with the original Item you purchased. End Products must not redistribute the original Item to any third parties in a manner that allows for the extraction of the original Item.
