That's ok if you like to keep it. 
It seems that it may be used to mean "*digital* image".
Here's an example from a translation I did today:
貴社にて作成可能な商品の画像データを頂ければ助かります。
Presumably, he's asking for pictures of the products to be sent as email attachments, 
rather than asking for the "image *data*" -- he wants to see the *products*, not 
examine the *data*.

GG5 (has it as a sub-entry). Also in Eijiro and 英和コンピューター用語辞典.

Don't mind if it goes, but we usually hang onto them if other refs have them.

As far as I can determine, 画像データ is not specifically *video* data. 
It seems to be just what you would expect from the individual entries for 
画像 and データ, and if that's the case, I think the entry for 画像データ 
should be deleted.

The guy answering this question clearly doesn't see it as "video data":
Q.英語に詳しい方、英訳お願いします。
写真データをＣＤ-Rに入れて、そのラベルを作成しています。
A. 詳しくはないけど、「Photograph data」又は「Photo data」が良いんじゃないの?
また、イラストなどを含む画像データなら、「Image data」が良いと思います。

On the following webpage, titled 画像データについて, 画像データ clearly refers to 
static images.
