you can use rex_date plugin to get Day&Month
(or you can use Browser object and ExecJs..)
so...if you have folder1,folder2...folder5...etc
and pic1.png,pic2.png..pic12.png..etc
you need to set url to something like this
"http://example.com/folder"&Date.Month&"/pic"&Date.Date&".png"[/code:2idijphs] [i]probably...[/i]
[b]Edit:[/b]
If you use for folder or picture 01,02,..09 format ...you need to use [i]zeropad(number,2)[/i]
[img="http://lookpic.com/O/i2/1701/4Wnc5YIj.png"]
[i]I use XAMPP server in example so url start with "http://localhost/"[/i]
so..URL
[code:2idijphs]"http://localhost/folder04/pic12.png"[/code:2idijphs]
becomes
[code:2idijphs]"http://localhost/folder"&varMonth&"/pic"&varDay&".png"[/code:2idijphs]
maybe would be best if you share link of today dummy pic..for testing...
