Hi Pratiyush, Realistically speaking there is no need to upload full size images in Tripoto. As long as the clarity isnt reduced (pixelated) it should be fine. Images you upload in Tripoto are for information, its not intended for printing. I hope my answer is satisfactory.
Hey Pratiyush, Guess you are opening those images in your Tripoto app after publishing ... Try opening the same in a desktop... And it also take some time to get uploaded and get clear ... I have experienced same and no need to worry about that ... An image of mine was 8mb and I could upload 5 or 6 of them altogether ... Happy Blogging and Happy Travelling Bro!!!
