543815 Pic mass upload/ Doc Library /Cat assign

Hello, For the small stock image website I am need need for some programming tasks: 1) My website script comes with batch upload for images whereby the uploaded hi-res images is split into smaller image sizes (i.e. medium, small size). Process currently stops or times out on my VPS server. I need someone with expertise in image batch uploading/processing to look and improve upload process - also entire new upload process is feasible. Outcome should be that photographers can upload and import 10,000 images with average 30MB in size with ease. 2) Photographers upload images to website, and they need to be able to attached documents to each image. A document library is need where photographers can upload documents and attached these to thousands of images quickly. (I imagine a screen - left side the uploaded document and on the right side little thumbs of the images) 3) Once images are uploaded they need to be categorized. I need window and process that will enable photographers to quickly assign 40 different categories to i.e 5,000 images. The system is based on smarty template and programmer needs to ensure that programing is done in alignment with template system. Many thanks
