I use INDEXU 5.1.0 and I added some custom fields from admin section Database/Alter , CHECKBOX Type with several options like that:
<img src='http://adress/images/visa.jpg' >Visa
<img src='http://adress/images/mastercard.jpg' >Mastercard

Now the problem is when i try to edit a link those checkboxes appear unchecked even though i cheched them before. This problem appears only if i have a link or an image in the options field.

Can you tell me what I'm doing wrong?
