#57 ResolveFilenameToAbsolute returns path relative to phpThumb

[Anonymous]

We use phpThumb 1.7.11 (beta) inside a folder of 3rd party libraries off root, the ResolveFilenameToAbsolute resolves the sourceFilename relative to the phpThumb folder, NOT the document folder. The simple fix is in phpthumb.class.php uncomment line 1071 and comment out line 1072 to change it back to the code used in 1.7.9.
