Roll overs and animated gifs
Posted on 2000-02-16
1 Am I correct in thinking that graphical images that are moving or blinking on the screen, is simply one *.gif file with many frames in it, rolling at a particular speed to give the perceived image of moving graphics, OR is it something else like a flash program?
2 What is the difference between animated gifs and Macromedia flash?
3 Also, with roll over images, where once the mouse moves over an image and it changes colour or shape etc, am I right in thinking that there are in fact 2 *.gif images there? If that is the case, do both gif images load with the page, surely if a site has many of these on there, wont it slow the site down when users try to load it?
4 How would you save the original image, as the right click save as option will only save the 2nd roll over images once you move over it.
5 Finally, how do some sites have a curved frame in the top left hand corner, and how do they have strips of different shaded horizontal lines like even here on EE? Is that a table created and then filled with colour?
