No. It doesn't work also.
In your example editor i get error messages:
image/tiffimage/tiff File format not allowed! Please contact site administrator.
for tiff
image/x-citrix-pjpegimage/jpeg File format not allowed! Please contact site administrator.
for jpeg
image/bmpimage/bmp File format not allowed! Please contact site administrator.
for bmp
image/x-citrix-gifimage/gif File format not allowed! Please contact site administrator.
for gif
But in my site/editor i have made some changes in Include_Mimetype.php and now it works with jpeg, gif, bmp, png.
But it still DOESN'T work with tiff or tif!
Please answer me, because i need a solvation for this problem. I can't upload tiff/tif images!
