You could make use of the compress pictures function in word.

In word 2007 it can be accessed by double clicking on a pic to access the picture tools. Then go to format tab and choose the compress pictures option (available on the left).  The same principle should apply to office 2010 or 2013. 

I am also not very good at computering, just like Sylvie and understand prefectly her problem. I do know how to compress pics. But sometimes it takes me hours, days, ages and no result. I even had to start from scratch with the same pics and then suddenly, for what reason I don �t know, but it worked.  It happened to me that a simple silly picture makes you losing so much time.

 

Is there a way to know the size of a picture before using it to avoid this ????

 

I do have worksheets that I have not been able to upload for this reason and on which I spend hours trying to down-size, reconstruct, all of no avail.

Thanks you two GI2gi and Monique for your answers. I know the size of each picture i chose, and when I made my pictionary  these pictures all added up to 880 ko or so, but it seems that if I put them in boxes , then it doubles the size of the whole doc!

 

Thanks anyway, cheers Sylvie!
