Ok. I'm going to detail how I fixed this problem, but some of you will not like it as it is tedious (what in web design isn't?) and you will have to work with an FTP client and your profiles database table. Here is how I fixed my greyed/missing Avatar pictures:
I first noticed that each of the Avatar pictures that were missing from the People tab (All Members), could easily be found in each person individual profile. Once I found the Avatar picture (Photo uploads when joining the site are titled Avatar) I looked at the date the member joined to get an idea of when they uploaded that picture that isn't showing. I then opened my FTP program and looked in the modules/boonex/avatar/data/images folder and verified that their Avatar picture was not in there...So I then navigated to the modules/boonex/photos/data/files folder and began the hunt for the Avatar picture within there. TIP: USE THE DATE THEY JOINED TO NARROW THE TIME IT TAKES FOR SEARCHING. Once you find the picture, you will see that there are many versions of it...the two that you should be concerned with are the ones labeled xxxi.jpg (32x32 small thumbnail, chat, extended views) and xxxt.jpg (64x64 larger thumbnail, blogs, browsing). When you find the two files, download them to your computer (with your ftp program) and then open your PHPMyAdmin (from within your cpanel of your webhost) and find the PROFILES database table, find the members name and look for the field of Avatar (there will be a number here), now you will want to rename the numbers on the photos that you just downloaded
Example: My Avatar's number is 23, so I will change the xxxi.jpg to 23i.jpg (keep that i), and the xxxt.jpg to 23.jpg (remove that t)
Then all you have to do is upload those new files to your modules/boonex/avatar/data/images folder and VOILA it will clear up that blank avatar!
This does not solve the problem for new members and the issue could theoretically return, but this is a quick makeup fix that has worked for two days for me so far. Hope this helps you all :)
