Beamer pause and grey not in order

Question

I have a slide that is produced by the following codes:

begin{frame}[plain]
begin{itemize}
item Current work 0
item Future works 1
item Future works 2
begin{center}
includegraphics[scale=0.35]{xxx.pdf}
end{center}
end{itemize}
end{frame}

Now I want to display the first item "Current work 0" and the graphics xxx.pdf at the same time, while grey out the two "Future works". Then on the next slide I want to display the two "Future works" items and grey out "Current works" and the graphics. Is there any way to achieve that?

The following MWE provides hidecontent[]{} that hides with a white transparent box. Optional transparency is set as (provided by Heiko's transparent package); default is 0.25 or 25%: documentclass{beamer}% http://ctan.org/pkg/beamer usepackage{transparent}% http://ctan.org/pkg/transparent setbeamercovered{transparent} newcommand{hidecontent}[2][0.25]{{% hidecontent[]{} setbox9=hbox{#2}% Store in box9 to obtain height/width transparent{#1}ooalign{usebox9crcolor{white}rule{wd9}{ht9}cr}}} begin{document} begin{frame}[plain] begin{itemize} item<1> Current work 0 item<2> Future works 1 item<2> Future works 2 begin{center} mbox{only<1>{includegraphics[scale=0.35]{example-image-a.pdf}}}% mbox{only<2>{hidecontent{includegraphics[scale=0.35]{example-image-a.pdf}}}}% end{center} end{itemize} end{frame} end{document} beamer doesn't adequately handle hiding of graphics, hence the use of hidecontent. This works well with rectangular content. Other content (textual, for example), is best dealt with by beamer itself.

I can suggest a less complicated way than what Werner proposed. It consists in one include and no change to your code, but you have to download a custom style that remedy to your problem.

Download fixpauseincludegraphics.sty and place it into the same folder as your .tex file.
Include the package with usepackage{fixpauseincludegraphics}.
(optional) Check out this post to understand how it works - long story short, this solution consists in an overloading of includegraphics to redraw the pictures using tikz to change the opacity according to the beamer transparency state.
