Cannot upload image in WIP

I have trouble uploading images in Works in Progress.

It says: “Upload failed”.

How large is the image?

The file size is at 2.49 mb.

Dimensions: 1920*1429

That would explain it. The upper limit for attachments is 2 MB. You can either reduce the size of the image (either in dimensions or by increasing compression) or use a service like to post a link to your image.
