package assumes writeable directory and should offer "easy" resize options

The nautilus-image-converter-0.3.0-0ubuntu2 package in Jaunty is a very useful package that arguably should be installed by default since it is perfect for newbies, or those who prefer the GUI.

However, it suffers from a few minor problems which if fixed would make it an awesome addition to the nautilus experience...

1) it assumes the directory the original file lives in is writeable. This can not always be assumed. A minor tweak would make it much more usable: when writing the resized file returns EPERM, pop up a file chooser and allow the user to save the resized file somewhere else (default: their desktop).

2) the menu it pops up is frankly alarming for naive users; they often don't know what 1024x768 pixels means. "scale" and "custom size" are also "too advanced" I would argue. These options should be retained, but the default should be to provide the naive user with a sane set of choice templates (a la gimps "File->New->Template") such as:

 a) resize image to a thumbnail (include description such as "very low detail - could be used for example as an email 'signature'")
 b) resize image to a low-resolution (description: " low detail - smallest size suitable for giving impression of the image")
 c) resize image to a medium-resolution (description: "medium details - good balance between file size and detail")
 d) resize image to a quarter/half/third resolution
 e) resize image by size: 100k, 250k, 500k, 1Mb, etc.
 f) resize image to: your current screen resolution
 g) et cetera...

Would be nice if it had an option to auto-correct the orientation using EXIF data (a la "exiftran -a") too.

Thanks for reading!
