הקובץ נשמר אוטומטית, אבל התמונה נעלמה מהעמוד.

ה־ is the Hebrew definite article, meaning the.

So:

• קובץ = file

• הקובץ = the file

• תמונה = picture / image

• התמונה = the picture / image

• עמוד = page
• העמוד = the page

Unlike English, Hebrew attaches the directly to the noun.

Because Hebrew often puts that meaning inside the verb itself.

נשמר already means something like was saved or got saved.
So Hebrew does not need a separate word like English was here.

That is very common in Hebrew:

• הקובץ נשמר = the file was saved
• not something like הקובץ היה נשמר for this meaning

That נ is part of the verb pattern, called נפעל.

This pattern often gives meanings like:

• passive: was X-ed
• middle/intransitive: got X-ed, became X, disappeared, etc.

So here:

• נשמר = was saved / got saved
• נעלמה = disappeared

You do not need to translate the נ by itself; it is just part of how the verb is built.

Because תמונה is a feminine noun, and Hebrew past-tense verbs agree with the subject in gender and number.

So:

• התמונה נעלמה = the image disappeared
• הקובץ נשמר = the file was saved

Here:

• נעלם = masculine singular
• נעלמה = feminine singular

Since תמונה is feminine, נעלמה is required.

קובץ is masculine.

That is why the verb is נשמר, the masculine singular past form.

If the subject were feminine, the form would be different. For example:

• התיקייה נשמרה = the folder was saved

So in this sentence:

• הקובץ → masculine
• התמונה → feminine

Here אוטומטית functions like an adverb: automatically.

In modern Hebrew, many words used adverbially appear in the feminine singular form, especially words ending in ־ית.

So:

• נשמר אוטומטית = was saved automatically

It is not agreeing with הקובץ as an adjective here.
If it were describing a feminine noun as an adjective, it could also be feminine, but in this sentence it is best understood as an adverb.

מהעמוד means from the page.

It is built from:

• מ־ = from
• העמוד = the page

When מ־ comes before a noun with ה־, they often combine:

• מ + העמוד → מהעמוד

So this is a very common Hebrew contraction.

Not always.

עמוד can mean:

• page
• column
• sometimes even pillar

The exact meaning depends on context.
In this sentence, because we are talking about a file and an image, page is the natural meaning.

It can mean any of those, depending on context.

Common possibilities are:

• picture
• image
• photo

In computer or website contexts, image is often the best translation.
In everyday speech, picture is also very natural.

אבל means but.

It connects the two clauses:

• הקובץ נשמר אוטומטית = the file was saved automatically
• אבל התמונה נעלמה מהעמוד = but the image disappeared from the page

So it marks contrast: one thing worked, but another problem happened.

Yes. Both verbs are in the past tense:

• נשמר = was saved
• נעלמה = disappeared

So the sentence describes two completed events in the past.

A common pronunciation is:

ha-KO-vets nish-MAR oto-ma-TIT, a-VAL ha-tmu-NA ne-el-MA me-ha-a-MUD

A smoother transliteration:

Hakovetz nishmar otomatit, aval hatmuna ne'elma meha'amud.

A couple of notes:

• התמונה is commonly pronounced hatmuna
• נעלמה has a slight break because of א: ne-elma

Not necessarily.

נעלמה simply means disappeared or vanished. It tells you the result, not the cause.

So the sentence says the image is no longer on the page, but it does not say whether:

• someone deleted it
• the page refreshed
• there was a bug
• it failed to load

It focuses on what happened, not why.
