You will just have to post some more to get more Steem Power after each payout and then when you get the payout go to your wallet and you will eventually after enough post reward have Steem and if you have some SBD you can click the arrow next to it then click market and trade some for some Steem then you will have some Steem. Once you have some Steem click the arrow next to it and select Power Up. This will send the steem into your Steem Power wallet which is what reflects your vote value. the profile image is different from a post so you have to use a different style link
