The image is invalid. Either the buffer is incomplete or the CRC is wrong. You can try with different image viewers, the lower part will miss, more or less depending on how tolerant is the reader. It is also important to tell us directly what you provide, like a png named as gif, it minimizes the time we need to test or analyze your problem. If you used imagecreatefromgif it will simply fail, so yes, which functions you use to open this image is important. I will check if returning false is a safe choice. It should be but I need to test it first.

Regarding what function I should use this is not the point - I created simple test case to illustrate problem. In the real script it is used completely different way. ------------------------------------------------------------------------ [2006-12-08 20:02:35] [EMAIL PROTECTED] Please provide a working link to the image. ------------------------------------------------------------------------ [2006-12-08 20:02:21] [EMAIL PROTECTED] You really should be using the imagecreatefromgif() function in this instance. The URL with an image seems to be down, can you provide a working URL for the file please. ------------------------------------------------------------------------ [2006-12-08 18:33:46] [EMAIL PROTECTED] Pierre, is E_ERROR really required in this case? ------------------------------------------------------------------------ [2006-12-08 18:25:56] pz at mysqlperformanceblog dot com Description: ------------ Getting the following error: PHP Fatal error: imagecreatefromstring(): gd-png: fatal libpng error: IDAT: CRC error in Note this is FATAL error for what should have been simply false result code from the function.
