Insert pictures HERE

Insert pictures HERE

I'm required to insert picture right in place. So I used [H] to figure. Unfortunately I have a lot of figures, and some mechanisms gets overloaded — and I get all figures stucked in the end of the section.
So I made it all as a minipage:
\def\Figure#1 {
  \vspace{2mm}
  \noindent
  \begin{minipage}{\linewidth}
    \centering
    #1
  \end{minipage}
  \vspace{2mm}
}
but this seems to be vertically justifying text:

If I insert clearpage at the beginning of the Figure — the problem is solved, but I get every picture starts at the top of the page — no matter if it fits in to the previous.
What would You do?
