Ok so I recently downloaded Gimp 2.8 and I already learned how to use it.I want to upload some of my files onto Tumblr but because of the file type (I think) the picture doesn't appear in my folders.So I think it might be the file type and I tried changing it to JPG and JPEG but didn't work so if anyone knows how to make it appear in my folder then please do say.
Thanks in advance!
