Id write this line of code as

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
createthumb($dir1,$dir.'/thumbs/'.$photo1,100,100);
createthumb($dir1,$dir.'/thumbs/'.$photo1,100,100);

Give that a try.

If my post is useful please add to my reputation.

well, if the problem is on line 48, the most sinister actors would be the 2 arguments '$dir1' AND '$dir/thumbs/$photo1'

- try outputting these strings before you call the function, and see what they contain.
e.g. echo "++$dir1++$dir/thumbs/$photo1++";

Your issue is your using single quotes ' instead of double quotes " as a string with a variable in it.
on line 48 you have:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
createthumb('$dir1','$dir/thumbs/$photo1',100,100);//Not working(problem here only)
createthumb('$dir1','$dir/thumbs/$photo1',100,100);//Not working(problem here only)

Try:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
createthumb("$dir1","$dir/thumbs/$photo1",100,100);//Not working(problem here only)
createthumb("$dir1","$dir/thumbs/$photo1",100,100);//Not working(problem here only)

the problem is, that when you use single quotes '$myvar' will actually be the string $myvar instead of the variable myvar. PHP does not parse inside single quotes, only double quotes.

hope that helps.

function createthumb() expect the first parameter to be image file name and i guess $filename is the directory path.
I think there is problem with you passing as $dir1, it seems to be made from $dir and some dir structure.Also what comes in $dirid is not been clear
