Submission
Brownie accepts only JPEG thumbnails for thumbpreview.
If webmaster submits thumbnail location and uploads thumbnail file at the same time - Brownie will use uploaded file.
New submission error messages:
- Thumbnail is not JPEG image means incorrect file type, filename extension doesn't matter
- Incorrect thumbanil size means image width or height has more or less pixels then required
- Thumbnail upload error means Brownie cannot read or save submitted thumbnail (all webmasters will get this error if you do not have free disk space)
- Thumbnail download error means Brownie cannot read or save thumbnail from submitted location
