"+" character is ignored

[cytec]

if i request a file with the name "image+stuff.jpg" adaptive-images.php trys to load "image stuff.jpg"

"+" is not a valid sign in the url and need to be escaped. you should use urlencode before putting filenames into a url:

urlencode("image+stuff.jpg") -> image%2Bstuff.jpg
