It looks like you are writing a replacement of the LunkUpload() function from
the file scripts/upload.php.

You can look how the function LinkUpload() works, it finds the attachment path
on the filesystem ($filepath) and its url address (the last $path) based on
the Attach:Group.Name/img.jpg markup and $UploadPrefixFmt and other variables.
Your own function could get all the information LinkUploads gets if you use
such a line to replace it:
$LinkFunctions['Attach:'] = 'MyGalleryFunction';
You should really try to use $UploadFileFmt and $UploadPrefixFmt because an
admin could have organized the uploads directories differently from what you
can imagine, for example
uploads/file.jpg
uploads/Group/file.jpg
uploads/Group/Page/file.jpg
uploads/Group.Page/file.jpg
uploads/Group/Group.Page/file.jpg
files/G/Gr/Group/P/Pa/Page/file.jpg see PerGroupSubDirectories
If you use $UploadFileFmt and/or $UploadPrefixFmt, you can have these paths
automatically, like LinkUpload() does.
Additionally, you could look at other gallery recipes, notably Mini has a
markup similar to Attach: although slightly more complex, and UploadPlus which
finds the attachments both in Group/ and in Group/Page upload directories.
