Upload form - Resize og Kun jpeg/jpg osv.?
Hej, jeg har det her script som jeg gerne vil have lavet ekstra på.Man kan oploade et billede, men vil gerne have at når billedet bliver uploadet bliver der lagt en kopi i samme mappe der f.eks. hedder "$filename_small" som bliver resizet til # * # px.
Og hvis det ikke er et JPG/GIF billede skal den fortælle at den ikke kan uploade... Nogen der kan hjælpe ??
