please 1 me

for each file uploadedfile in` doc.uploadedfiles`                 context.cache.remove(session.sessionid + "uploadedfile")                 dim stream stream = file.inputstream                 generatethumbnails(0.5, stream)                  dim documentimgname = file.filename                 dim imgdata byte() = new byte(viewstate("compressedimagedata")) {}                 dim documentsplit = documentimgname.split(".")                  dim imgname = documentsplit(0)                 dim imgext = documentsplit(1)                  stream.read(imgdata, 0, imgdata.length)                  viewstate("imgdata") = imgdata                 viewstate("filename") = imgname                 viewstate("fileextension") = imgext                  dim ms new memorystream()                  ms.write(imgdata, 0, imgdata.length)    next  private sub generatethumbnails(byval scalefactor double, byval sourcepath stream)     using image__1 = image.fromstream(sourcepath)              ' can given width of image want             dim newwidth = cint(image__1.width * scalefactor)              ' can given height of image want             dim newheight = cint(image__1.height * scalefactor)              dim thumbnailimg = new bitmap(newwidth, newheight)             dim thumbgraph = graphics.fromimage(thumbnailimg)              thumbgraph.compositingquality = compositingquality.highquality             thumbgraph.smoothingmode = smoothingmode.highquality             thumbgraph.interpolationmode = interpolationmode.highqualitybicubic              dim imagerectangle = new rectangle(0, 0, newwidth, newheight)              thumbgraph.drawimage(image__1, imagerectangle)              viewstate("compressedimagedata") = image__1.rawformat          end using     end sub

you can store image data after convert byte datatype below: 

dim ms new syste.io.memorystream me.picturebox1.image.save(ms, picturebox1.image.rawformat) dim byteimage() byte = ms.toarray

then can store byteimage() field wich type image or varbinary.
