Very new accounts have some strict restrictions to defend against spambots.
However, a very few upvotes that you receive by asking good and on-topic questions (or providing solutions to questions) will get you through such restrictions in no time.
For the very specific case of needing to post an image with < 10 rep, upload it to some hosting service such as imgur and link to it -- odds are a 2k+ rep user will promptly edit the question adding the image to it, as long as your question and image are on-topic.
As for tabular data, the matter is bit more tricky. The consensus is to drawn a code-formatted - or better, put it inside a <pre>
tag to don't trigger syntax highlighting, as commented by @ScottChamberlain - ASCII table to get a quick and dirty tabular data representation done.
Images are appropriate as well and often can represent tabular data better, though these are technically shorter-lived. Also, ensure that your question holds meaning without relying on external resources, so that the question does not get closed as Too Localized.
And about the question ban, see the canonical topic: What can I do when getting "We are no longer accepting questions/answers from this account"?
@Brad please reopen, I improved the question
and he might reopen the question. (You can't flag just yet)
