Re: [Dynapi-Help] Changing image source dynamically, smoothly?

[Raymond I. <xw...@ya...>]

Hi,

(Just got back from a short vacation)

Please see examples/dynapi.functions.imageloader.html
for an example on knowing when images havce been
downloaded.

The getImage() function also support the <a> link. See
examples/dynapi.functions.getimage.html for more
information.
