Any reasonably modern clip art library would do. InDesign can read most modern image file formats; and there is no special reason to search for something "for InDesign".
Thank you and point taken - but can you recommend any such clip art collection for download. Don't mind to pay it. yours Knud
Does "google" count as a recommendation?
I must admit I'm not a user of pre-made clipart. I guess before paying *anything* you should take a good look if it's not a bunch of lo-res jpegs, or the infernal file type WMF. EPS, in general, ought to be good, although "for best user experience" I always convert them to PDF by dropping them on the Distiller.
Thank you - but I am still looking for a specific recommendation - yours Knud
It is a rather vague request. Too vague for a "specific recommendation."
Office clip art? Religious? Animals? People? Silhouettes? Backgrounds? Nature? Design elements? Stock sites that charge? Free sites?
The list is nearly as vast as the internet.
Be specific in your Google search terms and you will find many, many hits.
Take care, Mike
