How to add image preview box?

[samukarna]

Hi,

First I'm sorry for bad english, I'm Brazilian.

How could I do to add a preview box in opportunities, accounts or contacts, equal to the preview box avatar for users?

Thanks for attention

Hi

It's rather related to developer help. Need to do it in javascript. You can replicate it. Use search by file contents by "avatar" keyword. Do the same for your entities.
