I’m experiencing the same issue…
I went looking in the plugin’s code.
In simple-share-buttons-adder\inc\ssba_admin_bits.php
Where the code is ‘preparing’ the array that gets saved back to the database for SSBA’s options/settings:
function ssba_settings() {
...
// prepare array
$arrOptions = array(
'ssba_image_set' => $ssbaPost['ssba_image_set'],
...
The current code is not ‘preparing’ the array for all of the custom image URLs…
Something similar to the following code needs to be added that will take the data in the post object for each of the custom images and also add them to the $arrOptions array.
It is this $arrOptions array that eventually gets saved back into the database…
'ssba_custom_email' => $ssbaPost['ssba_custom_email'],
'ssba_custom_google' => $ssbaPost['ssba_custom_google'],
'ssba_custom_facebook' => $ssbaPost['ssba_custom_facebook'],
'ssba_custom_twitter' => $ssbaPost['ssba_custom_twitter'],
'ssba_custom_diggit' => $ssbaPost['ssba_custom_diggit'],
'ssba_custom_linkedin' => $ssbaPost['ssba_custom_linkedin'],
'ssba_custom_reddit' => $ssbaPost['ssba_custom_reddit'],
'ssba_custom_stumbleupon' => $ssbaPost['ssba_custom_stumbleupon'],
'ssba_custom_pinterest' => $ssbaPost['ssba_custom_pinterest'],
'ssba_custom_buffer' => $ssbaPost['ssba_custom_buffer'],
'ssba_custom_flattr' => $ssbaPost['ssba_custom_flattr'],
'ssba_custom_tumblr' => $ssbaPost['ssba_custom_tumblr'],
'ssba_custom_print' => $ssbaPost['ssba_custom_print'],
'ssba_custom_vk' => $ssbaPost['ssba_custom_vk'],
'ssba_custom_yummly' => $ssbaPost['ssba_custom_yummly'],
