This is the way Tripoto encourages travellers to share good, original and accurate content on the platform. For every content you publish, you are awarded points based on the quality of blog. Even your participation in the forum gets you credit points. So, what does it mean for us? You could exchange/ use these credits to book customised trips available on the platform :)
Yes there is . You can upload as many as you want . But photos have to be of very good quality and you need to write some description about the pics so that it is a value add to the reader. you won't get any credit for just uploading the pics
