Si el reportaje hubiera incluido fotos del barrio, la portada habría sido más interesante.

This sentence is a classic past unreal conditional: it talks about something that did not happen in the past and imagines a different result.

Structure:

• Si + past perfect subjunctive → si el reportaje hubiera incluido...
• conditional perfect → la portada habría sido...

So:

• hubiera incluido = had included
• habría sido = would have been

A very literal breakdown is:

• Si el reportaje hubiera incluido fotos del barrio = If the article had included photos of the neighbourhood
• la portada habría sido más interesante = the cover/front page would have been more interesting

In standard Spanish, after si in this kind of hypothetical sentence, you normally use the subjunctive, not the conditional.

So Spanish says:

• Si hubiera incluido...
• Si hubiese incluido...

But not standard:

• Si habría incluido...

This is one of the most important patterns to remember:

• si + imperfect subjunctive → for present/future unreal situations
  
  • Si tuviera dinero, compraría un coche.
• si + past perfect subjunctive → for past unreal situations
  
  • Si hubiera tenido dinero, habría comprado un coche.

Yes. Hubiera and hubiese are both correct here.

So these mean the same:

• Si el reportaje hubiera incluido fotos del barrio...
• Si el reportaje hubiese incluido fotos del barrio...

In modern Spanish, hubiera is often more common in everyday use, but hubiese is perfectly natural and correct.

Incluido is the past participle of incluir.

Here it appears in a compound tense with haber:

• hubiera incluido = had included

So:

• hubiera = auxiliary verb from haber
• incluido = past participle

This is the same pattern as:

• he comido
• había salido
• habrían llegado

Reportaje usually means a report, feature article, or news feature, depending on context.

It is not always the same as English report in every situation. In Spanish, reportaje often suggests something more like:

• a magazine feature
• a newspaper feature
• a journalistic piece with detail and background

So in this sentence, el reportaje is probably a journalistic article or feature.

It can mean either, depending on context.

Portada commonly means:

• the cover of a magazine
• the front page of a newspaper
• the front cover of a publication more generally

In this sentence, either cover or front page could fit, depending on what the learner was told the sentence means.

Because de + el contracts to del.

So:

• de + el barrio → del barrio

This contraction is mandatory in normal Spanish.

The only common exception is when el is part of a proper name, for example:

• de El Escorial

But here el barrio is just a normal noun phrase, so it becomes del barrio.

Barrio usually means neighbourhood or district.

In Spain, it often refers to a local area of a town or city, sometimes with a sense of community or local identity.

So fotos del barrio means photos of the neighbourhood.

Spanish often leaves out the article when speaking in a general, non-specific way about plural nouns after certain verbs.

So:

• incluyó fotos del barrio = included photos of the neighbourhood

This sounds natural because it just means some photos of the neighbourhood, without needing to specify exactly which ones.

You could say unas fotos del barrio, but that gives a slightly stronger sense of some photos. The version without the article is very normal and idiomatic.

Because interesante is an adjective ending in -e, and adjectives of that type usually do not change for masculine vs feminine.

So:

• un reportaje interesante
• una portada interesante

Both use interesante.

Only the number changes:

• una portada interesante
• unas portadas interesantes

Because the sentence is making a comparison with how the cover actually was.

It implies:

• the cover was interesting to some degree, but
• it would have been more interesting if the article had included neighbourhood photos

So más interesante means more interesting, comparing the real version with the imagined alternative version.

Yes. You can put the result clause first and the si clause second.

For example:

• La portada habría sido más interesante si el reportaje hubiera incluido fotos del barrio.

This means exactly the same thing.

The main difference is emphasis:

• starting with Si... highlights the condition first
• starting with La portada... highlights the result first

When the sentence begins with the si clause, a comma is normally used:

• Si el reportaje hubiera incluido fotos del barrio, la portada habría sido más interesante.

If the main clause comes first, Spanish usually does not use a comma before the si clause:

• La portada habría sido más interesante si el reportaje hubiera incluido fotos del barrio.

Not if you want the same meaning.

• habría sido más interesante = would have been more interesting
  This refers to an unreal result in the past.

• sería más interesante = would be more interesting
  This normally refers to a present or future hypothetical situation.

Since this sentence is about a past situation that did not happen, habría sido is the correct form.

Yes. That is exactly what this structure implies.

The sentence suggests:

• the report did not include photos of the neighbourhood
• as a result, the cover was not as interesting as it could have been

That is why this tense combination is used: it presents an imagined past alternative to reality.

It is grammatically quite advanced, but completely normal Spanish. You could see or hear it in:

• journalism
• formal writing
• conversation
• criticism or commentary

Native speakers absolutely use this structure in real life when talking about hypothetical past situations. It is not unnatural or overly literary.
