I have created a Dropbox account for the purpose of compiling all the converted/resized/finished custom portraits in one place, easy to download and add and modify.
Dropbox is a cloud storage utility that allows multiple users to all link and modify a central collection of files. Its all drag and drop and easy to use. Just keep in mind that what you do effects all other users, so deleting files will delete files for all. Make sure you use a copy/paste command and not a MOVE command which will delete files.
There are 2 ways to access the dropbox. You can use the web based utitlity allowing you to access the dropbox without downloading any software and operating like a normal site. The download allows for more features and easier use but is not required. Either method uses the below info for log-in.
