Hi,

i have dowloaded and utilized this script http://www.dynamicdrive.com/dynamicindex4/cmotiongallery.htm

I want to add two arrows on either side of the images and when I go on I start scroll. I have added pictures but can not seem to understand what function to call onMouseOver event.

Can you help me please?

Thanks in advance

Your script is perfect, but I want to understand what you've added in the script (Scroll functions and ...)???

Thanks

I added


function Scroll(ud){
scrollspeed=ud||0;
if (ud>0){
clearTimeout(righttime);
if (movestate!="left") moveleft();
}
if (ud<0){
clearTimeout(lefttime);
scrollspeed*=-1;
if (movestate!="right") moveright();
}
}

hi great information thanks, i have been trying to figure this out for some time by looking at how others do it.

But when i do this however it tells me that ud is not defined. what is ud please so i can adapt the function to my site... or did i miss something ..

what i did was i added the function same as you in the same please in the file. then i made left and right image gif files. then when i use them i say onClick or onMouseover. but it tells me that ud is not defined...

any idea thanks ?

the value of ud is passed to the function by the inline event calls


<img title="left" src="http://www.dynamicdrive.com/dynamicindex4/dynamicbook1.gif" border=1 width="20" onmouseover="Scroll(5);" onmouseout="Scroll(0);">
<img title="right" src="http://www.dynamicdrive.com/dynamicindex4/dynamicbook1.gif" border=1 width="20" onmouseover="Scroll(-5);" onmouseout="Scroll(0);">
