# Why Does the New Editor of OSM Display an Error When Uploading Images?

> Getting a file extension error when uploading images in the MoEngage OSM editor? Remove extra dots from file names added by social media apps.

## Problem

When trying to upload images in the OSM campaign's new editor, the following error occurs:\
"File extension is not supported."

## Explanation

* Social media apps add characters with a period (dot) to the beginning of image file names before uploading them.
* MoEngage interprets any text after a dot as a file extension, which causes the error.

## Solution

To fix this error, remove the dot from the file name.

## Example

* When additional characters are added at the start of the image file name, it appears as: "Snapinsta.app\_431485390\_745691364337715\_8350453286241390781\_n\_1080.jpg".
* After removing the dot from the file name, the resulting file must resemble:\
  “Snapinstaapp\_431485390\_745691364337715\_8350453286241390781\_n\_1080.jpg“.
