How to find an Object_id ?

[S_L_J_van_der_Horst]

I submitted some items on the story board on graffiti (owner RossDonihue). After submitting location, text and image both location and text were displayed but not the image. A few days ago i managed to look into the data of the storymap and found the Object_id's from the items. But now i can't reproduce my steps to do so.

Any idea ?

I found a way to retrieve the Object_id's (one by one)! 

Note : windows 10

After choosing an item (blue pins) the description appears on the left.

Next i click the right mouse button on the description an select "Inspect (Ctrl+Shift+I)".

See above, right side. In blue the tag with Object_id 1156.
