In addition to what other persons have contributed so far, I advice you focus on your ability to add value to community and do not spam the forum as a result of chasing activity/merit in order to post your images rather take it slightly and show full working (You need Research , Learn & add value) so when people visit your profile (including me) and see something impressive they would have no option than to leave merit with you and in the end you would realize that it's more easy to get merit than you think now.
