[magick-users] memory allocation failed when open an image with url

[Santa Santa]

Hi,

When I use tries to open an online image and scale it, I will get an error:

Caught exception: ImageMagick: Memory allocation failed `
http://tbn3.google.com/images?q=tbn:1qmj4LZwmBhaIM:http://www.nv.doe.gov/library/PhotoLibrary/xx-012.jpg'
@ resize.c/ScaleImage/2510

I tried with convert binary which works.
This is a very small image, so I think the memory should be enough.
I guess it's other problems causing this error.
Anyone has any ideas?
Thanks a lot

Shane
