Toggle Images

Question

APEX issue :
When I'm loading the page I'm executing a javascript to load images in the page. I'm using checkbox and tick images and these images are placed in 9 show and hide regions. I'm executing a javascript in onload and this script loads all the images during refreshing. Since the server is very slow. When I'm refreshing the page I can see images loading starting from 250 on the right hand side down in my browser. Before all the images gets loaded if I click the hideshow region the image lodding gets abandoned and images in the region looks like it's partially loaded I can find some missing images too.
Can anyone please help me in this issue.
Note : the same code works fine in another server which is very fast.
For example see the below script and I've used a similar one but the query has more images and I'm deciding the type of image to be loaded in an onload event.
I've designed my code based on the below example taken from "Dennes Kubicek" blogspot.
<script type="text/javascript">
function toggleImage(x)
x.src = (x.src.indexOf("#WORKSPACE_IMAGES#FNDCANCE.gif") >
-1)?"#WORKSPACE_IMAGES#Fndokay1.gif":"#WORKSPACE_IMAGES#FNDCANCE.gif";
</script>
2. Image Source:
<img src="#WORKSPACE_IMAGES#FNDCANCE.gif" onclick="javascript:toggleImage(this);">
3. SQL Query:
SELECT ename, job, mgr, sal,
'<img src="#WORKSPACE_IMAGES#FNDCANCE.gif" '
|| 'onclick="javascript:toggleImage(this);toggleImage(im'
|| ROWNUM
|| ');">' image,
'<img src="#WORKSPACE_IMAGES#FNDCANCE.gif" id="im'
|| ROWNUM
|| '">' image2
FROM emp

Hi guys:
I came searching for this same problem and only happened upon a solution (at least for me) very accidently. In my case the "softness" doesn't seem to be actually linked to the "quick preview" toggle.
When I pull down the "view" menu from the top of the screen, I pass the "quick preview" command and go down to the bottom to "Proofing Profiles". The profile for the proofing was set to one of many of my printer's profiles, which was not calibrated, yet, for my mac. I selected, instead, a previously saved calibration setting (one that I made using the simple calibration wizard under the monitor system preference) specifically for my monitor, and the viewer image changed to look exactly as the one in Browser thumbnail; sharp and detailed.
I certainly hope that this may help you. As I said, this is not based on in-depth knowledge of this program, just trial and error, so may not apply to your situation.
Good Luck
