Fix Large File Photo Upload to FTP within app. Currently timing out before completed. Fix Thumbnail Quality.

I have existing apk that allows me to create multiple inventory worksheets for inventory. Each worksheet is associated with photos of inventoried items. There are times where I must upload up to 10,000 photos to the server. Lately the upload will "time-out" before it finishes uploading. I then have to start over again from the beginning. I've used an "outboard" apk called AndFtp to upload the photos, and it works perfectly...However I need this ability within my apk. I am not sure if program is loading too many photos and crashing the memory before it has time to upload? I just need it to work! Next, the quality of my thumbnail images are terrible. I need them to be the same size. Not sure if the thumbnail image is created from the original image. Please review within the app. Work needing done: 1. Re-code photo uploading engine so that it WILL NOT timeout before all file are uploaded. 2. Allow for "User Selected" photos from the list to be uploaded manually if needed. 3. Fix thumbnail image quality.
