The straightforward answer is Yes, you should upload a photograph.
Although there are quite a few users who do not upload a photograph, ThaiLoveLines.com has introduced a Pro Photo policy which has meant that we have begun restricting the use of the site by Standard Members who do not upload a photo within 72 hours.
It has been shown over and over again that profiles with photographs received an increased response to non photographic profiles by over 200%. Many members on ThailoveLines.com will not respond to profiles where a photograph is not shown.
Our ThaiLoveLines.com support office is happy to assist any user to upload a photo in anyway we can. Please feel free to contact us if you need help in anyway with this issue.
