I'm assuming you have opened Disk Utility and you can see your disk image in the list
Make sure your

Select your disk image

Resize that mofo
Double-click the disk image in the list to mount it

All it takes is a short Google search to discover the answer. Ray's Weblog has a solution:
A Sparse Bundle Image will increase in size automatically but will not shrink automatically. Before shrinking the sparse bundle, mount it and empty the trash to get rid of any deleted items from the image.
Unmount the image and follow the commands below.
To compact (image size stays the same):
hdiutil compact ~/Documents/filename.sparsebundle hdiutil compact -help (for a list of options)
To increase the image size (eg., 20G to 30G)
hdiutil resize -size 30g ~/Documents/filename.sparsebundle hdiutil resize -help (for a list of options)
Mount the image then do a Get Info on the Volume to see the new size.
