No graph or image shown on Cacti overview page

[petercal]

I have just installed Cacti and are starting to learn ho to set it up. I have defined a few snmp polles to hosts, an they works Ok.
My problem is, when i click the Graph tab (Console,Graph) i see like an overview page with thumpnail pictures and links to the different hosts, but i dont see any pictures or graph on this page, just a X where the picture should have been !!

When i click on the links i see the graphs OK.

Can anyone help ?

thanks and rgds

Cacti Version 0.8.7b

Problem Solved !!
I have selected wrong RRD version under Console settings
I found the answer when i looked at System utilities, Tecnical support

Thanks,
