The word "picture" comes from Latin pictura, from pict- past participle stem of pingere "to paint" (SOED). So while the extension of the word "picture" to photographs and movies is somewhat stretched, the artists' reaction is also incorrect (by over-reaction). What they paint are most assuredly "pictures", no matter what they "depict".

There are other words to distinguish different types of "picture" when necessary:

pictiúr "a picture, painting, photograph, movie" (usually clear from context).
pictiúr (daite) "a colour picture, painting"
olaphictiúr "an oil painting" (and to preempt Lughaidh, pictiúr ola would be more natural)
pictiúr uiscedhatha "a water-colour painting"
pictiúr (reatha) "a motion picture, movie"
líníocht "a drawing"
grianghraf "a photograph"
scannán "a movie"
péinteáil "painting" (the house, etc.)
péintéireacht ola "oil painting (as a process)"

(Crossed with An Cionnfhaolach)
