do you have to open the file in read mode first though?

i dont understand why this wouldnt just make the variable have a value of "myfilename.gif" , by putting single quotes around it, does it make it special?

The variable "$file" is being filled with the quoted string. You would use this in a completed project more because it allows you to change things later down the road.

The "filesize" function does not require you to open the file to check the size. A good use for this is to check for filesize before you open it to ensure the file is intact and won't crash your system.

This is pretty cool this may come in handy thanks so much. What version of PHP is this for, I have 5.0 or so locally, but my host is 4.1.3 (I think) and some things I read in my PHP 5 book wont apply to my host. :(

it'll work in 4 easily
whats the difference between single and double quote in php?

PHP will parse code in double quotes, but not single quotes. Using single quotes for echo'ing will make your php code faster, though not really noticable.
