Memory Size For File Uploads Options

[CraigVanSant]

I'm getting this error while trying to upload and image around 600k. Uploading of images only seems to work it the image file size is close to 100k. How can I get that limit increased to at least 10 megs.

The site url is riversidebia.org and here is the error

Allowed memory size of 16777216 bytes exhausted (tried to allocate 2550 bytes) in /data/12/1/152/55/1152218/user/1224160/htdocs/eventadmin/image_upload/image_functions.php on line 86

thanks
