Files & images
There are two different situations involving files, and it helps to know which one you mean when you ask. Your AI handles the technical side either way.
1. Files your visitors upload
When you want people using your app to upload something — a profile photo, an attachment, a document — just describe it:
"Let visitors attach a photo when they post a message, and show the photo with their message."
These uploads are private by default: your app decides who can see them and serves them securely. This is the right choice for user-generated content like avatars and attachments.
2. Images you provide yourself
When you want to ship an image as part of the app — a logo, a background, an icon, a hero photo — that's a different kind of file. Tell your AI you want to add it:
"Use this image as the site logo in the top-left corner."
If your AI can see or fetch the image, it can place it for you. These developer-provided assets are public (anyone viewing the app can load them, like any normal website image) and they get a permanent web address.
Your app's icon (favicon & app logo)
Every app gets an icon automatically — the little picture that shows in the browser tab, and the one your phone uses if someone adds the app to their home screen. Out of the box it's a simple letter-on-a-colour icon based on your project name, so a brand-new app already looks finished. You don't have to do anything.
When you want your own brand there, give your AI a logo:
"Here's our logo — use it as the app's icon."
Hand it one square image (a PNG or an SVG works best) and onvibe turns it into every size and shape the different devices need — browser tab, iPhone home screen, Android install, and so on. A logo change can take a few minutes to show because browsers remember the old one for a while.
Which one do I want?
| You want… | That's… |
|---|---|
| Your users to upload photos/files at any time | visitor uploads (private) |
| To add your own logo, icons, or background | provided images (public) |
| A gallery people contribute to | visitor uploads (private) |
| Decorative graphics that are part of the design | provided images (public) |
Good to know
- Individual uploads have a size limit and each project has a total storage allowance — see Limits & good to know.
- If you don't say which kind you mean, your AI will usually infer it from context; if it guesses wrong, just clarify ("no, I mean files my visitors upload").
