 * I’ve been having problems with image management in 2.5 and I can’t figure out
   how to fix it. The images are on the page but when I click on them to see them
   larger an error comes up. I was wondering if anyone could take a quick look and
   see if they can tell me how to fix this?

 * THANK YOU SO MUCH FOR ANY HELP – looking for a job right now and if my portfolio
   doesn’t work that doesn’t look good.

 * It looks like you just upgraded to 2.5. I believe the function that is undefined
   is supposed to be in wp-includes/media.php
 * I have checked media.php in my installation and found the function you are missing,
   wp_get_attachment_image() in media.php, so I’m not clear why you don’t have it.
   You can try re-loading media.php on the chance that it may be corrupted, but 
   if it were I think you’d be seeing other issues also.

 * I’m not sure why it would be doing this…
 * I redownloaded 2.5 and deleted and re-added the wp-admin and wp-includes on the
   server and it’s still not working so I’m not sure what to do now…

 * I have been looking in the codex for answers, it is recommended that you re-load
   wp-settings.php. You’ll find it in your root directory for your blog. be sure
   that you save a copy of your original when you do something like this.

 * You’ll want to take it out of maintenance mode if you would like others from 
   this forum to join in.

 * OH YES! Sorry! I’m pretty sure what fixed the problem was reloading the wp-settings.
   php file. Thanks for the help mechx1! I had never replaced the old file when 
   I updated because the update only told me to replace my wp-admin and wp-includes
   folders. The wp-settings.php file was in the root directory and so I didn’t replace
   it with the new file included in the upgrade files for 2.5 – however I have done
   so now and it is resolved!
 * Thanks so much for the help!

 * mechx1, you are awesome!!! I’ve been having a really hard time with the uploader.
   I did everything the mod’s sticky post said to do and still no luck. I even tried
   to disable the flash uploader but it still sucked. Now everything is working 
   great with your tip. I hadn’t replaced the settings php because it was never 
   mentioned in the upgrade outline.
 * Thanks again!!!
