[Clipart] [Open Clip Art Library] duplicate files

[noreply at openclipart.org]

I've been writing in about uploading svgs and pngs. I have now uploaded both pngs and svg files for all of my images. The images that only have one file are duplicates, and I think, because the files now exist in two places, the system won't let me delete them. So I am wondering if someone on the other end might be able to. Thanks.
