The ability to display a portfolio on your WordPress site depends on the type of plan you have.
Art Galleria's website portfolio feature generates an iFrame that you can embed on other sites. Only paid WordPress plans support embedding iFrames.
In summary:
The free version of WordPress blocks the display of embedded iFrames.
Paid WordPress plans allow you to display iFrames using the Custom HTML block or one of the free iFrame plugins.
