Upload one, make one from a description, or bring one back from a page on the
web. Sizes, formats and the rest are handled.

## Three ways to get a picture

**Upload.** Drag it in. There is a progress bar, and it is real — it holds at
the end while the description and the crop are worked out.

**Generate.** Describe what you want and pick a size. This costs credits, and
the price is shown before you commit to it.

**Import.** Give the AI a picture it can see on a page and ask it to bring it
into your library. It arrives as a real file of yours, free, like an upload.

## Everything lives in Files

One library per site, under **Site → Files**, with three tabs — Library,
Generate, Upload. Anything that picks a picture opens the same library, so there
is one place your pictures are and one way to choose one.

## Sizes and formats are not your problem

When a picture goes onto a page it goes with everything a browser needs to pick
the right version: several widths, and modern formats with a fallback for
browsers that cannot read them.

You do not choose a size. Upload the photograph at its full resolution and the
right version is served to each visitor.

## Descriptions

Every picture gets alt text — a short description for anyone who cannot see it,
and for search engines. One is suggested when you upload, and you can edit it.

It is worth editing. A suggested description says what is in the photograph; a
good one says what it is doing on your page.

## The focal point

Set the point of a picture that must stay visible — a face, a sign — and crops
keep it in frame rather than cutting through it.

## The trash

Trashing a picture takes it out of the library, out of every picker, and out of
reach of the AI. **It keeps being served**, so a page that already uses it does
not break.

Emptying the trash is the only real delete.

## Deleting a picture that is in use

You are told which pages use it, and allowed to go ahead. A picture already
placed on a page is written into that page, so removing the file leaves the page
pointing at something that is gone.

One thing to know: a deleted picture can still be served for a while from the
cache in front of the site. Deleting is for tidying up, not for taking something
down urgently.
