it's not really diff sizes being posted .... the site is in a state of transition .. A BIG STATE .. LOT'S OF SCENERY ... and the "math" isn't finalized
until further notice I would continue uploading as usual .. 4:3 ratio .. 1600x1200 preferred
just be wary that uploading full size & resolution ‘worthy pics’ as this also makes them more of a viable target for rippers to use in commercial enterprises.....
