Images overview
The four image slots in the creator: Title bar, Toolbar, Inactive tabs, and New tab.
In the Awetheme Chrome Theme Creator, images come in four slots (or you can use one Fullscreen background image that is split automatically). Images are bundled into the theme package—you cannot use external URLs.
Preview size, target size, and display resolution
On desktop, Awetheme automatically detects the display area available to the browser. This excludes space reserved for the macOS menu bar, Dock, Windows taskbar, and similar system controls.
The detected size becomes the creator's default Preview size and controls fullscreen wallpaper cropping and export dimensions. After publishing, it appears on the theme details page as the Target work area. In the marketplace, My screen shows themes with similar dimensions, while My screen (exactly) requires both dimensions to match.
On phones, the creator does not use the mobile screen as a Chrome theme target. The initial size and Reset to default size use 1440 × 900, and stock image searches use that selected desktop target size. Chrome themes are applied to desktop browser windows, not the mobile Chrome interface.
On Retina and other high-density displays, the detected size may be smaller than the resolution advertised for the monitor. This is expected; use the size detected by Awetheme without adjusting it manually.
Four image slots in the creator
| Creator label | What it affects | Technical name on export |
|---|---|---|
| Title bar | Window title bar and tab strip | theme_frame |
| Toolbar | The toolbar row with the address bar | theme_toolbar |
| Inactive tabs | Background of inactive tabs | theme_tab_background |
| New tab | New tab page background | theme_ntp_background |
If you do not want separate uploads, turn on Fullscreen background: one wallpaper is cropped into the Title bar, Toolbar, New tab page, and related areas on export.

Chrome spec image keys the creator does not expose yet
These are often used for Incognito, unfocused windows, overlays, and similar cases. The creator does not offer separate controls for them yet; Chrome falls back to defaults when they are unset. If you write a theme package by hand, you can still add them by technical name.
| Description | Technical name |
|---|---|
| Window frame (window in background) | theme_frame_inactive |
| Window frame (Incognito) | theme_frame_incognito |
| Window frame (Incognito, window in background) | theme_frame_incognito_inactive |
| Inactive tabs (window in background) | theme_tab_background_inactive |
| Inactive tabs (Incognito) | theme_tab_background_incognito |
| Inactive tabs (Incognito, window in background) | theme_tab_background_incognito_inactive |
| Frame overlay | theme_frame_overlay |
