 * All.
 * So, I just spent WAY too long trying to fix a problem and I finally did it! Just
   in case there are others out there trying to do the same thing and can’t find
   the answer online… well, now… here it is.
 * I am writing my own custom plugin to be used with WordPress MU 2.9.2.
 * My plugin allows a ADMIN panel that users can upload an image that will be stored
   into its own table in MySQL database (under WordPress MU scheme). I have written
   a matching Widget that will then pull the related images directly from the database
   and display to website visitors.
 * The problem I was having was… I could upload images into via my WordPress ADMIN
   panel screen that were less than approx 60 Kb (kilobytes) in size. Anything **
   over** that… just didn’t do anything. It was like I never made the form POST.
   For the longest time I thought it had to do with my PHP file upload limits (**
   which do need to be set**). In the end, it turned out I was using a MySQL database
   field “BLOB” that is only 64K in size. So, I changed my database field from “
   BLOB” to “**MEDIUMBLOB**” and IT WORKED!!! “MEDIUMBLOB” has size of 16MB and “
   LONGBLOB” has 4GB. Thanks to the following URL I found that on: [http://osdir.com/ml/php.database/2002-06/msg00020.html](http://osdir.com/ml/php.database/2002-06/msg00020.html)
 * Also, make sure you have the appropriate settings for the following files:
 * PHP.ini
 *     ```
       ; Maximum allowed size for uploaded files.
       upload_max_filesize = 120M
       ; Maximum size of POST data that PHP will accept.
       post_max_size = 100M
       ```
   
 * MY.ini
 *     ```
       key_buffer_size=25M
       max_allowed_packet=16M
       ```
   
 * GOOD LUCK and I hope this helps someone else!
