Hello and welcome to you and your sister. I've followed you both. Thanks for verifying in the other post too. The best way to verify is to link back to your steemit account from your other already existing online accounts. Post something about your steemit account on your instagram for example.
The photos you posted can still be faked. A video would be better. Some people will post a video of themselves writing out the steemit account. Those cannot be photoshopped of course.
I have a post about how to verify if you're interested in checking it out. It is very important to verify here. The more famous the person is, the more important it is. The more valuable their content outside of Steemit is, the more important it is too.
Here's some information I saw with new people to help them get started...
There are a ton of other webpages to help you with Steemit. Here are some of the best for beginners:
https://steemd.com/ (This site is used to keep track of your voting power and other stats. You do not want to run out of voting power, and you only get so much per day. I keep my voting power around 80% for example.)
https://steem.makerwannabe.com/ (This site will tell you who follows you, who unfollows you, and who mutes you. It is great for meeting new people too. I regularly check it to see who has followed me to see if I should follow them back.)
https://steemit.chat/ (This site is the official chat webpage for Steemit. There are Discord channels too, but I usually stick to the official site. Come in to network and meet new friends. You can directly message people there too, so it makes it easier to communicate with your closest friends.)
Oh yeah, there are a lot of bots on here. If you see a cookie cutter reply, especially to your intro post, it is almost certainly a bot. Check the account's reputation. If it is low, I would recommend just ignoring them. Everything is public on Steemit, so you can go look at an account's comments and replies. Are they all the same? It's a bot.
Adding photos to your account as a new Steemian may be confusing at first too. The easiest way it to click to "Submit a Story." Once in there, use the built in Steemit tool to upload an image from your computer. Below the posting window, you will see "Insert images by dragging & dropping, pasting from the clipboard, or by selecting them." Click on the blue text. Once the image is uploaded, you can copy and paste the link into your account settings.
Again, welcome, and I've followed you! If you have any questions about getting started, look me up on the chat site.
