<!-- wp:toolset-blocks/field {"customField":{"label":"Image Couverture","value":"image-couverture","categories":["text","url","image"],"type":"image","fieldOptions":null,"is_repetitive":false,"is_created_by_types":true},"fieldType":"standard","postProvider":{"value":"__current_post","label":"album actuelle"},"toolsetField":{"label":"Image Couverture","value":"image-couverture","categories":["text","url","image"],"type":"image","fieldOptions":null,"is_repetitive":false,"is_created_by_types":true},"toolsetFieldGroup":"toolset_custom_field|albums","toolsetFieldSettings":{"output":"normal","titleAltCombo":"","align":"none","size":"thumbnail","sizeCombo":"","proportional":"true","resize":"proportional","padding_color":"transparent","toolsetCombo:padding_color":"","class":"","style":"","title":"%%TITLE%%","alt":"%%ALT%%","width":"","height":""},"toolsetShortcode":"[types field='image-couverture' output='normal' align='none' size='thumbnail' proportional='true' resize='proportional' padding_color='transparent' title='%%TITLE%%' alt='%%ALT%%' ][/types]"} -->
<div class="tb-field" data-toolset-blocks-field="1" data-last-update="1.4">[types field='image-couverture' output='normal' align='none' size='thumbnail' proportional='true' resize='proportional' padding_color='transparent' title='%%TITLE%%' alt='%%ALT%%' ][/types]</div>

[types field='image-couverture' output='normal' align='none' size='thumbnail' proportional='true' resize='proportional' padding_color='transparent' title='%%TITLE%%' alt='%%ALT%%' ][/types]</div>
