Hi

When doing resizing on the image, I got the error below
gd-png:  fatal libpng error: IDAT: CRC error
gd-png error: setjmp returns error condition 22014/05/06 10:45:55 [error] 6137#0: *4879 gdImageCreateFromPngPtr() failed while sending to client, client: x.x.x.x, server: my.hostname.com, request: "GET /r/5270146_201306300555490402.png HTTP/1.0", upstream: "http://172.16.0.78:80/5270146_201306300555490402.png", host: "backend", referrer: "referer page"

My configuration 
                expires 1y;
                image_filter_buffer 5M;
                image_filter resize $1 $2;
                proxy_pass http://backend1/$3;
                error_page     415   = /empty;

Please kindly help
