your file being locked , preventing deleting it. image.fromfile method locks file used create object until image object disposed of. in case, image file remain locked until dispose of upimage.

move file.delete after you're done image , work. in code below, added using statements each variable disposed of (and unlock file), , moved delete statement outside of using block (after image objects disposed of).

using(system.drawing.image upimage =  system.drawing.image.fromfile(server.mappath("~/imageuploadcenter/" + foldername1 + "/") + name))      using(system.drawing.image logoimage = system.drawing.image.fromfile(server.mappath("~/pages002248xc54/uploadimages/logonew.png"))) using (graphics g = graphics.fromimage(upimage)) {     g.drawimage(logoimage, new point(upimage.width - logoimage.width - 10, 10));     upimage.save(server.mappath("~/imageuploadcenter/" + foldername + "/") + name); } file.delete(server.mappath("~/imageuploadcenter/" + foldername1 + "/") + name); 

image.fromfile method (string)
