Thread:Project:Support desk/Memory Error When Trying To Upload Image To Wiki

Mediawiki 1.16.4, PHP 5.3.25, SQL 5.5.32

Am trying to upload an image file to my Mediawiki. It's a .png file, 6012px x 1153px and weighs in at 202KB. I've uploaded 'large' images before without a problem. On this occasion, I get the following error.

Fatal error: Allowed memory size of 52428800 bytes exhausted (tried to allocate 20795508 bytes) in /home/locallan/public_html/includes/media/Bitmap.php on line 213

Advice would be welcome.
