Hi Garret,

I've inspected that there is some of missing images in the file:
JoomlaFolder/images/blog_shared
as you upload an images, it should consist of multiples size ( original, small, icon, thumbnail etc.)
May I know how you upload the image? or did you accidentally delete the images in the folder?
Because I've tried to upload a new image in the shared media, seems it was shows correctly.

Thanks for updating Garret, glad that your issues are resolved now
