Uploading your photos is a critical step — anticipating connection conditions before the event is essential to ensure quick publication and avoid unpleasant surprises in the field.
Choosing a good connection #
The upload speed depends directly on your network connection. There are three possible situations:
- Fibre optic (recommended) — ask the organiser for access to the event's fibre WiFi. This is the fastest and most reliable solution.
- 4G — use the "Personal Hotspot" option on your phone. Be sure to check that the phone network is 4G at the event location before relying on it.
- ADSL — to be avoided as much as possible for large volumes, as upload times can become very long
Estimate upload time #
The time required depends on the number of photos and their average size. Here are some guidelines:
10 MB photos (RAW/high resolution)
| Number of photos | Total weight | 4G (10 Mbps) | Fibre (100 Mbps) | ADSL (0.5 Mbps) |
|---|---|---|---|---|
| 10 | 0.1 GB | 1 min 20 | 8 seconds | 26 min |
| 100 | 1 GB | 13 min | 1 min 20 | 4 hours 26 minutes |
| 1,000 | 10 GB | 2 hours 13 minutes | 13 min | 44 hours+ |
| 10,000 | 100 GB | 10 p.m. | 2 hours 13 minutes | — |
3 MB photos (standard JPEG)
| Number of photos | Total weight | 4G (10 Mbps) | Fibre (100 Mbps) | ADSL (0.5 Mbps) |
|---|---|---|---|---|
| 10 | 0.03 GB | 24 seconds | 2 seconds | 8 min |
| 100 | 0.3 GB | 4 min | 24 seconds | 1 hour 20 minutes |
| 1,000 | 3 GB | 40 minutes | 4 min | 1:20 p.m. |
| 5,000 | 15 GB | 3 hours 20 minutes | 20 minutes | 66 hours+ |
1 MB photos (compressed JPEG)
| Number of photos | Total weight | 4G (10 Mbps) | Fibre (100 Mbps) | ADSL (0.5 Mbps) |
|---|---|---|---|---|
| 10 | 0.01 GB | 8 seconds | 1 second | 2 min 40 |
| 100 | 0.1 GB | 1 min 20 | 8 seconds | 26 min |
| 1,000 | 1 GB | 13 min | 1 min 20 | 4 hours 26 minutes |
| 10,000 | 10 GB | 2 hours 13 minutes | 13 min | 44 hours+ |
If you only sell your photos online #
Take the time to ensure you have the right conditions before starting the import. Of course, the sooner your photos are online, the more likely you are to sell — but this goal should not cause you to compromise on connection quality. An unstable upload can cause errors and significantly slow down processing.
⚠️ Always test your connection at the event location before committing to a publication deadline — 4G coverage can vary greatly depending on location, especially in mountainous or rural areas.
💡 For large volumes (1,000 photos or more), plan to import your photos in successive batches rather than all at once, in order to limit the risks in the event of a network outage.
