<P>Hi Marian,</P>
<P>The background on the gifs might be clear or white, if you paste into MW it doesn't actually matter because the transparency is lost anyway. To restore transparent backgrounds, just double click the shape in the shape centre, then pour in the transparent colour from the colour palette onto the background. The point is that as long as the background is plain, you can make it transparent easily. Also if you find an animated gif, you <STRONG><EM>could </EM></STRONG>take it apart to make an animated turtle.</P>
<P>Also, depending on the version of MW you are using, the transparent colour might take a little bit of locating; the earlier versions use (if memory serves me) the lightest shade of white.</P>
<P>Filetypes - you could write a short book on the question, but in brief, here goes...</P>
<P><STRONG>GIF</STRONG> (Graphic Image File) have a max of 256 colours, can have transparent areas, are used in animations, are often logos, cartoons, text.</P>
<P><STRONG>JPEG </STRONG>(.jpg -Joint Photographer Expert Group) can have up to 16 million colours, can be compressed to lower the file size, are often used for photographs. If you copy and paste a big, colour-rich jpeg into MW (especially earlier versions) you will notice that the colour depth is reduced.</P>
<P><STRONG>PICT</STRONG>(Mac format) PICTs are Mac produced bit maps and object image files... basically, these are images made on a mac.</P>

<P>Hope this helps, good luck</P>

<DIV></DIV>About those gif files... Is the background white or clear?
<DIV></DIV>Also, could you give me the concise differences between a .jpg .gif and .pict
<DIV></DIV>I kind of know this, but not well enough to use it to my advantage.
