Facebook timeline wallpost image cropped after like -

-

i have facebook button on website, half year now. used og tags visualize like. tested thoroughly, showed on 'basic' wall, 'timeline' wall in news feed.

but al of sudden, when likes page, image being cropped on timeline wall. original image 200px x 200px, because facebook developer tool mentioned these dimensions.

i don't think image dimension issue, because 96x96 image being cropped. cropped mean top , bottom part of logo cut-off.

now have old post (march 2012) image not cropped , post (few days ago) image cropped. difference between 2 url of image:

one original image ok: https://fbexternal-a.akamaihd.net/safe_image.php?d=aqcahhvmadrtku6h&w=155&h=114&url=http%3a%2f%2fwww.poobies.fr%2fsite%2fimg%2fsocialmedia%2fsocialmedia_logo_fr.png

and 1 image cropped: https://fbexternal-a.akamaihd.net/safe_image.php?d=aqcahhvmadrtku6h&w=155&h=114&url=http%3a%2f%2fwww.poobies.fr%2fsite%2fimg%2fsocialmedia%2fsocialmedia_logo_fr.png&cfs=1

see parameter &cfs=1?

is there option or og parameter makes sure image not being cropped facebook?

thank you

i did research , found problem combination of using png , having image white background.

here's original png (90 x 90 px) white background gets cropped:

then same png darkened background uses full image size

jpgs , gifs white bgs worked fine

as side note, facebook didn't when served images through https.

it nice if facebook document these changes make, alas.
