I am trying to capture the appropriate Latin term to describe an ‘idea’ - something that you imagine or picture in your mind.
Thank you.

This may be a little more broad than what you want, but the first word that comes to mind to me is sententia. From the Lewis and Short dictionary entry for sententia(bolding is mine):
a way of thinking, opinion, judgment, sentiment, thought, notion, purpose, determination, decision, will, desire
Cicero uses it to mean thoughts in Cic. de Orat. 2.56:
qui ita creber est rerum frequentia, ut verborum prope numerum sententiarum numero consequatur, ita porro verbis est aptus et pressus, ut nescias, utrum res oratione an verba sententiis inlustrentur:
Translation by J.M. Watson in 1860:
After him, in my opinion, Thucydides has certainly surpassed all historians in the art of composition; for he is so abundant in matter, that he almost equals the number of his words by the number of his thoughts; and he is so happy and judicious in his expressions, that you are at a loss to decide whether his facts are set off by his style, or his style by his thoughts;
As cmw has indicated, there are different kinds of ideas e.g. an opinion = "opinio"; "sententia" (see Adam's answwer); a suspicion = "suspicio"; a guess = "coniectura" and then an ordinary idea = "species", "forma", "imago", "notitia".
If you look these up you will find interesting, alternative meanings: taking just one, (approaching your desire for "something that you imagine or picture in your mind") "imago" = "image", "likeness", "echo" & "ghost" (as well as "idea"!) (Oxford)
In Lewis & Short (net) as well as definitions there are usually references to the Latin literature with attestations of use.
