Hi sama55, thanks for the input.
1) if user has set another avatar, this avatar is shown instead default
2) if you click on "show all images" it displays all images. you can change default 3 days to whatever days you like. See info box. Just add to URL: ?days=30
3) true, open issue
4) yes, comment it out, this is just for my theme.
5) good point, will add a check if image blobid exists in page. It is up to the user to delete all images at once or one-by-one.
I will change n°4 and 5 tonight and commit it to github.
