Not all pictures loading up WordPress

Probably the most important bit is

which seems to come from

Maybe you can try to set your memory limit a little higher:
ini_set('memory_limit', '64M');
Depends on your current server configuration. If you're unsure you should consult your hosting provider support.

Santo, This was one of the possibilities I mentioned in your last question, that your server instance is running out of memory while processing the images.

Depending on how your hosting is set up you either need to:

1. Edit the php.ini file:
memory_limit = 256M
max_execution_time = 300

2. Use ini_set in wp-config.php to set these settings if you can't edit the php.ini file.

ini_set('memory_limit', '256M');
ini_set('max_execution_time', '300');

Caveat: These settings are very high, check with your hosting provider to see what limits they may have set on these. You should be able to determine what they are currently set at also by looking through your hosting documentation. Try setting the values high, and then bringing them down until it stops working, then you will be able to find the level at which it should be set without having it set too high.

Hi Santo,

Without denying that there is a problem with allocate memory shown on log file.
Timthumb (thumb.php) only use allocate memory when the image is <strong>being</strong> resized and put the result in cache folder.

So When user go to a page contain resized images, it will check if the image resized exists on cache folder and show it, if not exists then the image will be resize and it will use some of memory to store temp image resize.

In webkit base, I see the image didn't load correctly on the browser, and result on 500 internal server error. This could be cause by memory limit too. No matter what number of memory set, its useless if your server memory is limited and should be share with other user.

My suggestion for this problem,
1. Set the cache higher for timthumb script, on thumb.php you can see in the beginning of code:

define ('CACHE_SIZE', 250); // number of files to store before clearing cache

change CACHE_SIZE higher than currently set for example:

define ('CACHE_SIZE', 450); // number of files to store before clearing cache

2. Deactivate any thumbnail resize features and resize the image manually.

3. Use Wordpress plugin for cache like <strong>Denzel Chia</strong> said on [[LINK href="http://www.wpquestions.com/question/show/id/2375"]]your question before[[/LINK]]. WP Super Cache is a good option.

4. Move to a new server/hosting, which is not a good option at all.. :D

Hope this help..
