maxso Posted January 25, 2009 Author Share Posted January 25, 2009 now it says Parse error: parse error, unexpected T_VARIABLE in /home/www/********.com/profile.php on line 6 The line is $watermarkfile = '/8.png' Quote Link to comment Share on other sites More sharing options...
maxso Posted January 25, 2009 Author Share Posted January 25, 2009 I think I have messed it up lol. All i wanted was for when someone uploaded a file, it would instantly put a watermark onto the file. Quote Link to comment Share on other sites More sharing options...
aeonsky Posted January 25, 2009 Share Posted January 25, 2009 Your code works perfectly. Puts a watermark in the middle of the background picture. Just make sure you end all statements with a colon. This is your problem. $sourcefile = 'background.jpg'; $watermarkfile = 'watermark.png'; $saveFile = 'new.png'; Make sure to change the names. Just one thing, why do you have variables being passed to the function if you are just gonna overwrite them later? Quote Link to comment Share on other sites More sharing options...
