HTTP Error Fix Can now upload large images

2011-08-07 by 10 Comments

When uploading large images over an approximate size (~2500×2000) I was encountering the HTTP Error message when trying to crunch the image (which ultimately fails and doesn’t produce the smaller pre-defined image sizes).

After trying several solutions, the following appears to have solved it for my setup, once and for all – add this to your .htaccess file:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 
php_value memory_limit "128M"
 
#BEGIN Image Upload HTTP Error Fix
<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>
<IfModule security_module>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>
<IfModule security2_module>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>
#END Image Upload HTTP Error Fix
view raw .htaccess This Gist brought to you by GitHub.

In short, it massively bumps up the allowed memory limit, and also tries to turn off some security aspects for the file that deals with the uploading, under different module setups.

      Either you’ve copied and pasted incorrectly, caused some other grammatical error, or your server didn’t like the commands. Either way, I can’t help debug from the zero useful information you’ve given me.

        i have edited my htaccess exactly above mentioned.But it show 500 internal error page when viewing the website. only watermark reload plugin makes this problem.when its inactive there is no problem.But i definitely need one watermark plugin.every watermark plugins shows the same error(when uploading images it shows http error)

          It might be that your watermark plugin has attempted to add it’s own rules to the .htaccess file, and your replacing it with the code above has caused it to throw a 500 error.

          Maybe point the author of the plugin to this post, and see if they can spot anything in my code which they know will cause problems with their plugin functionality?

      Maybe your host has disabled ceertain bits of code from working under .htaccess? If so, then your best bet is to raise it with them, tell them the solutions you’ve tried, and ask them to provide a fix instead.
