Hosted Thumb Sizes ?

[Dugmor]

I will be making new thumbs for the hosted galleries....

What are the any sizes that are the most popular ?

Right now I have.

88 x 88
100 x 133
125 x 150
150 x 200
150 x 225
160 x 160
125 X 150

Should I remove any of those and make different sizes ?

Does anyone use Hosted Thumbs to for Hosted Galleries anymore... or should I not even bother ?
