not require imagery to be uploaded when submitting an idea
When someone has an idea, a concept, and they happen not to be a visual or graphic artist, your requiring the upload of an accompanying image prevents and declines ideas LEGO might want to execute.
If imagery is required, please consider producing two ways to submit ideas so no one is prevented from sharing their concept.
Unfortunately, the requirement of having to include an image of your submission will not be changed.
The expectation of LEGO Ideas Product Ideas is that all submissions must show a built LEGO model.
Flashy, photoshopped images are not necessary of course. However, images must be of a good quality, crisp and clear and on a neutral background.
