img and anchor tags are defenitely inline elements; not block level.
Block-level elements
Headings, paragraphs, lists, or tables are "large" structures containing other blocks, inline elements, or text (but see nesting rules, below). They are usually displayed as independent "blocks" separated from other blocks by vertical space (margins).
Inline or text-level elements
Hyperlinks, citations, quotations, or images are "small" structures that represent or describe small pieces of text or data. They may contain only text or other inline elements, and are usually displayed one after another on a line within the block that contains them.
