hello, sorry to disturb you... I was actually quit good in ICT in college but I just can't remember anything. =(

Can somebody help me...
I need that a part of an url changes.... so for example i have the url : http://www.mywebsite.com/wp-content/uploads/2015/06/01.jpg

I need that the "01" changes in every row. so the next one would be
http://www.mywebsite/wp-content/uploads/2015/06/02.jpg
http://www.mywebsite/wp-content/uploads/2015/06/03.jpg
http://www.mywebsite/wp-content/uploads/2015/06/04.jpg
and so on....

until for example 56...

Would be very nice if somebody could help me =)
Thank you
