Replacing or Removing a Logo
Replacing a logo touches two screens, and the order matters.
Your default slots store a reference to a file, not a copy of it. Delete the file and the reference stays behind, still pointing at something that is no longer there. Nothing clears it for you, so everything that was using that logo starts rendering a missing image.
Doing it in the right order avoids that completely.
Before You Begin
- The new logo file ready to upload
- You know which slot it is for — light background, dark background or icon
Steps
Upload the new file first
In the drive, open this brand's logos folder and upload the new logo. Leave the old file exactly where it is.
Both files will sit in the folder together for a few minutes. That is fine, and it is the whole trick — the old logo keeps working until you have finished switching over.
Repoint the slot
Go to Marketing > Graphics > Brand Logos. Both logos are now listed.
Find the new file and press the slot it should fill — Light, Dark or Icon. The badge moves off the old card and onto the new one. Press Save Defaults.
From this moment everything Zyntro produces uses the new logo, and nothing depends on the old file any more.
Now delete the old file
Back in the drive, delete the old logo from the logos folder.
It is safe to do this now precisely because no slot points at it. Check the Brand Logos screen afterwards if you want to be certain: three badges, all on files that are still there.
Result
The new logo is in use everywhere, the old file is gone, and no slot is pointing at anything that does not exist.
Why the order matters
| If you... | What happens |
|---|---|
| Upload, repoint, then delete | The logo swaps over cleanly and nothing breaks at any point |
| Delete first, then upload and repoint | Between the delete and the repoint, the slot points at a missing file — anything produced in that window comes out with a missing logo |
| Delete and never repoint | The slot stays broken indefinitely. Nothing warns you; you find out when a customer sees a document |
Important: This applies to any logo file you delete, not only one you are replacing. If you delete a file from the logos folder, check the Brand Logos screen afterwards and confirm all three slots still point at files that exist.
Tip: Removing a logo without replacing it? Point the slot at another file you already have before deleting — even an imperfect one. An empty slot means anything needing that variant gets no logo at all, which is usually worse than a slightly wrong one.
Warning: If a logo has already started showing up as a missing image on a document, a page or an email, this is almost certainly the cause: the file it pointed at was deleted. Go to the Brand Logos screen, nominate a file that exists for that slot, and save. The surfaces pick it up from then on, though anything already generated keeps the broken reference.
