I use RadRotator 2008 Q2 (but have verified the problem to also exist in 2008 Q3) with TransitionEffect Fade to rotate between a number of images. It seems to work fine in IE 6 / 7, but Firefox (both 2 and 3) sometimes displays a problem concerning height. Parts of many or all images are displayed at the same time and moved around instead of the visual effect of changing the images.
In IE the following tag is rendered:
|<div id="ctl00_content_banner1_ctl00_rotator_frame0" style="overflow:hidden;">
Firefox renders something like following when it displays correct:
|<div style="overflow: hidden; height: 1660px; width: 964px;" id="ctl00_content_banner1_ctl00_rotator_frame0">
...and something like this when the error occurs:
|<div style="overflow: hidden; height: 36px; width: 964px;" id="ctl00_content_banner1_ctl00_rotator_frame0">
The actual image size is 974 x 379 pixels, and is output using an .aspx-page with Response.ContentType = "Image/jpeg", which can perhaps make loading times unpredictable as the image might have to be resized from a large file on disk on the server.
Anyone have an idea about this issue, any suggestions on workarounds?
