Hi Beto,
first of all I noticed that this kind of request is already available in this forum. You should search a similar case before open a new topic. In fact a solution valid for you could be already explained here.
Moreover to obtain help you have to better explain your case.
Anyway if you are working with WebRatio 7 you can refer to the logic reported as answer here: https://www.webratio.com/forum/question-details/display-image-in-an-hierarchy-component.
In particular:
Check if in the Properties View of the attribute, that refer to the image, is set the "Content Type": in the Domain Model, select the attribute present in the Entity -> move to the Properties View -> choose the "image" value in the "Content Type" property.
In this case the image is stored in an Entity as blob Attribute. In the Acme project (https://www.webratio.com/store/item-details/acme) you sould find all you need.
I hope this will help you.
