Hi!
According to the document Working with [Blob Fields of Base View](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_data_sources_and_base_views/working_with_blob_fields_of_base_views/working_with_blob_fields_of_base_views#setting-the-content-type-of-a-blob-field) it is possible to display them appropriately.
When I tried it, I created a table that contains a column with the blob type. In Virtual DataPort Administration Tool I created a base view from this table and made sure that this base view has a primary key defined.
It is important that this view has the primary key for this job defined, because otherwise, the web services won't display any element for the blob column.
After the web service is configured and deployed, you can open the link to the web service and the table will be displayed. If you want to open the image just click on the hyperlink in the row.
I hope this helps!
