You can’t directly upload images to steemit so if you are looking for an upload option, there isn’t one.
Instead you have to load images to a 3rd party site and then link the image in your story.
set up an account and upload the images you want to use in your post.
click on your image share icon and then copy the ‘direct link’
Now, on steemit, click on submit a story.
The first field is the title bar, this is where you put your posts title and will be displayed in the main steemit feeds.
the next big field is the where you write your story. The first line of your story will show up in the steemit feeds.
This panel is also where you put links to your images.
As mentioned above, copy the direct link for the image from postimage.org and simply paste it into your story.
your first image in the story will also be the image that shows up as a thumbnail when you post your story.
at the bottom of the page is the ‘tag’ field. this is where you decide which categories your post will show up in (also known as tags or topics)
So if you want your post to show up in the ‘introduceyourself’ category/topic then you simply type introduceyourself into the tag line.
you can choose up to 5 categories, leave a space inbetween each tag.
