I know ping(), but I don't know how to decide which one is too large. It should depend on the memory used by IM. If it consume more then 1GB, I think it's too large. So is there some formula to calculate the memory used by IM for one image approximately? For example, the image's dimensions is 5000 ...

I used ImageMagick-6.7.0 to resize lots of pictures and got one large exceptional picture. It's about 2.7MB. To resize it, Imagick++ used about 1.5GB memory.

Dear Drarakel, it works, thank you very much!

By the way, for CMYK pictures in such cases, use a generic SWOP profile, Dear administrators, why don't you put USWebCoatedSWOP.icc file into "http://www.imagemagick.org/download/del ... ofiles.zip"

After converting, the image's colorspace is still CMYK. Other photos could be convert successfully, only this photo failed. How to convert the "sepecial" photo ? ~/ImageMagick/bin$ ./convert file_4.jpg -profile SRGBSPAC.ICM 1.jpg ~/ImageMagick/bin$ ./identify -verbose 1.jpg | grep Colorspace ...

By using both of the functions as follow, the gif image size was reduce.
thumbnails = OptimizeImageLayers(thumbnails, exception);
OptimizeImageTransparency(thumbnails, exception);

"Lets now use the "-layers", method 'OptimizeTransparency' (Added IM v6.3.4-4) to replace any pixel that does change the displayed result with transparency.

So Is there any method for me to deal with these pictures using IM ?

It's a GIF image file. when IM opens it, it throw the exception "e=ImageMagick: Corrupt image `2AD9A180-F37A-459F-B056-A4C71CE31445.gif' @ gif.c/ReadGIFImage/1316"
So, it's a corrupt image, but it can be viewed and edit under widows xp.
