Hey There, Welcome to the forum!
Making a project page with images only is possible but unfortunately there is no way around the gap between images. If you are set on making it out of just images you may want to edit each set/section of images together in photoshop or whatever software you are using so there is only gaps between project page videos, etc.
While making a page just out of images can look alot nicer in some instances, adding text to the page can have some benefits as well. For example, bloggers/journalists writing about your project may copy and paste content onto another page so they can use that information as a source. If you are using just images, copying text will not work. It's just something to think about
If you have any other questions, feel free to reply here, send me a pm, or email me using the email in my forum signature. I am always available to discuss your project and answer your crowdfunding questions.
All the best with the campaign!
Kind Regards,
Jake
