How To Change Entire Selection of Avatars?

Very new to this software and I must say, I feel like a little kid in the candy store!  So much to do, and so much creativity.  I am in desperate need to find out how can I can change my entire set of avatars that came standard with Dolphin 7.  They do not match my theme or look and feel.  I have searched in the Market, but I didn't see much.  Do I have to have them created from scratch or are there other options to choose/purchase that I may have just overlooked?  I have a military theme to my site and these avatars just don't match.  Please advise.  Thank you.

You can change the default set of avatars by overwriting the files under /modules/boonex/avatar/ready/. You may need to clear your cache directories for your changes to take affect.

I've tried this but get an error when selecting an avatar... see attachment

There aren't any set options that I know of to select or purchase, although there are tons of free avatar sets out there. To replace the existing set, resize your new avatars to 32x32 pixels and upload, as mentioned to the folder  /modules/boonex/avatar/data/ready in your file manager. You will either need to delete the existing avatars or save them as the same file names in order to overwrite them. And don't forget to clear the cache after you are done. (You may also need to reload your browser or clear the browser cache) Your new avatars will then show up as you want.

I figured it out on my own with a little trial and error. Thanks for the reply, tho.
