Hi,

yes, when you upload a file, the server will put it in the /tmp
directory.
This file will be destroyed at the end of the script by PHP, so you need
to save it (in this case you'll create a blob with that file) before the
end.
Your script will receive the /tmp filename, the original filename, the
file size and the mime type in 4 variables.
If you want to know the height and width of an image, use the
imagesize() function on the /tmp file.
