Resizing Very Large Images - ImageMagick Question

[matthewamzn]

I have imagemagick running on my forum installation. I want to be able to resize really large images that people upload (photographers). It's resizing images up to about 2500 pixels wide. But anything bigger than that, and my forum gives this error message:

"The Dimension limits for this filetype are 800 x 600. We were unable to resize your file so you will need to do so manually and upload it again. Your file is currently 8858 x 2182."

I'm not sure where to find the actual error that is occuring. I've set php.ini to upload large files. Does anyone know how to make imagemagick resize these really large images?

This has been resolved. I had to edit the config.php in my vbulletin forum to allow for the increased dimensions.

Searching for that error message ( part of it anyway ) in google brought me to this:

Max width or height for uploaded pictures (pixels)

Limits the height and width dimensions of the pictures that are uploaded. Resizing large pictures requires a lot of memory and consumes CPU resources.

It seems this is a config directive that you can increase.
