What Simple Booth's own help page states for Simple Booth HALO templates, as we read it on 13 November 2026:
| Overlay | PNG with transparency |
|---|---|
| Background | margin background JPEG or PNG |
| Sizes stated | size depends on the booth configuration; the app shows the recommended pixel size |
| Photo positions | fixed by the chosen layout; print needs reformatting |

The guide we read is for HALO 4.x. In HALO 5.0, layouts are built in the Layout Designer on the online dashboard.


Check the recommended pixel size in the app's Design Panel first. If it matches one of the folders listed below, upload that overlay.png (a PNG with transparency) or background.jpg (a JPEG margin background). If it doesn't match, the files need resizing first; we don't resize them for you.
Not yet tested by us.
Each size is a folder with overlay.png (the design with see-through photo windows; it goes on top of the photos), background.jpg (the same design with no windows; it goes behind them) and preview.jpg (sample photos dropped in; don't load this one). All files are 300 dpi. A README.txt gives every canvas size and every photo box (x, y, width, height in pixels), with the load steps for the booth app you pick first. We don't make Darkroom .xbdr files, and there are no 5x7 files.
The samples on this page show the look; they are not downloads. To get files, type your own event: you see 3 designs in about a minute, with no account and no card (one free try a day; on a busy day you may see sample designs instead). Press "Get the files" on the one you like and we email you the zip (one free pack per email per day). The designs and the link are deleted after 24 hours. Designs are made by AI, so check the spelling and the date before you print.
