I have looked for documentation on this and can't seem to find what I need, but I am unable to upload images in .tiff format, I have tried "Set MIME type based on file suffix" with no luck.
I read this page at https://doc.tiki.org/Why-File-Uploads-May-Fail
and couldn't really glean much from it though I did learn alot.
I do have tiff and tif whitelisted.
Any suggestions on uploading .tiff or .tif are greatly appreciated. Thanks community!
