Error messages

When I upload a picture of my toy/resource, I get an error message 413.
This is usually because the file size is too big, or you are using a file format that SeTLS doesn't support.
File formats accepted are jpeg, png, gif* or webp. Try converting your picture to one of these files and reuploading.

*gif files are not printable so we recommend against this file type if you use a label template that includes item image.
