html - PNG images not loaded -

i developper of www.zundelcristea.com website.

for reason, png images not being loaded, although exist on right path, right permissions (664, other file on server).

my .htacess doesn't contain related images, nor folders. have no idea else can check.

locally, .png loaded normally. suggestion appreciated

[edit] nothing in error_log

you transferred them in text mode:

$ pngcheck -v mobile-menu-icon.png   file: mobile-menu-icon.png (425 bytes)   file corrupted. seems have suffered dos->unix conversion.   errors detected in mobile-menu-icon.png 

the first 8 bytes of png file contain following values:

(decimal)              137  80  78  71  13  10  26  10 (hexadecimal)           89  50  4e  47  0d  0a  1a  0a (ascii c notation)    \211   p   n   g  \r  \n \032 \n 

from png specification, "rationale": signature both identifies file png file , provides immediate detection of common file-transfer problems. first 2 bytes distinguish png files on systems expect first 2 bytes identify file type uniquely. first byte chosen non-ascii value reduce probability text file may misrecognized png file; also, catches bad file transfers clear bit 7. bytes 2 through 4 name format. cr-lf sequence catches bad file transfers alter newline sequences. control-z character stops file display under ms-dos. final line feed checks inverse of cr-lf translation problem.
