You are resaving a JPEG. You'll be compressing twice. Why don't you try to directly save the data obtained from the URL to a file on the SDCard. Don't do any compressing. Just a direct save of the JPG file from Flickr.
After you've done that, you have a file (on the SDCard) that contains an exact copy of the image on Flickr. Get hold of the fully qualified file-name of this file. Then you insert a new image into the images' content provider: values.put(MediaStore.MediaColumns.DATA, fullyQualifiedFileName); ... ... Uri uri = mCtx.getContentResolver().insert (Images.Media.EXTERNAL_CONTENT_URI, values); On Feb 1, 4:22 pm, michael <michael.d.peder...@googlemail.com> wrote: > Bump; the post got held up for 2 days due to moderation. > > On Jan 30, 4:53 pm, michael <michael.d.peder...@googlemail.com> wrote: > > > > > Hi, > > > I am working on an app that displays photos which are downloaded from > > Flickr.
