We run a number of WordPress sites for different clients as well as my own blog on WordPress.com.
On several installs we experience the same problem with tables set up to display photos disappearing.
An example is on this site: http://www.prasarnmitinternationalprogram.com
If you click on the faculty teacher tab at http://www.prasarnmitinternationalprogram.com/faculty/ you will see a nice page of staff photos and text.
Clicking on the Thai language equivalent (last tab on the right) at http://www.prasarnmitinternationalprogram.com/thai/faculty/ you will see a blank page.
While the text is Thai, the images are the same as on the English language page. We get the same white screen problem if we copy and paste the English language content into the Thai page.
We've increased php.ini memory to 128Mbytes
We've installed TinyMCE Advanced and that fixed the problems on some sites/pages but not on others.
I have the same problem on my WordPress.com blog once I install a moderate amount of text and 12 or 14 cells containing images.
All of the images are no larger than 1024 x 768 at 72dpi.
The fault repeats itself irrespective of what template is being used and whether plugins are disabled or not.
The standard response from WordPress is that our table code is wrong - typically:
<table border="0" cellspacing="0" cellpadding="0" width="430"> <tbody> <tr> <td align="center" valign="top">Photo coming soon 170</td> <td align="center" valign="top">Photo coming soon 170</td> <td align="center" valign="top">Photo coming soon 170 </td> <td align="center" valign="top">Photo coming soon 170</td> </tr> </tbody></table>
While WordPress so-called "Happiness Engineers" are quick to claim it's our code, no one is able to say what is wrong with it. It's now getting to the point where we will soon start moving our clients over to Joomla-based systems if we can not solve this problem.
We've had this problem on WordPress.com for over 18 months, and the problem seems to be getting worse with each update and WordPress are keeping their heads in the sand over it.
