image gallery with selection of images and action on them

Producing a webpage with some simple back-end functionality. The webpage displays images from a folder on the server, allowing some actions on selected images. Thumbnails are generated on-the-fly (or cache) from the server folder. (Stub script for this exists.) The folder can hold a large number of pictures (more than 50 up to 500). Subfolders shall be supported. No Upload functionality needed. Grid style for thumbnails. By clicking thumbnails images (mid-sized) are displayed in lightbox (or similar) style. It must be possible to split a larger number of pictures across “pages”. Info shown together with thumbnail in grid are: name, dimension, original file size. (with on/off option to display on page). Multi-Thumbnails can be selected/deselected per folder for further actions (if possible with rubber band as in explorer). Actions on selected thumbnails are: - Download in zip file (use existing zip command on server) - Download in PDF (use existing jpg-2-pdf alike command on server) - Display selected pictures in slide show (lightbox) - Show in a text table the selected files with relevant information from the table. (i.e. name of file, size of picture (dimension, file length). - Options per action define what files go in the zip file and PDF (e.g. only thumb files, mid-sized, full size, original image, layout PDF) The selection and deselection of pictures and the applied actions shall be state-depended for one folder. I.e. selection and action shall work accross the whole folder. It shall be possible to “save” the selection “i.e. the knowledge which files to consider” on the server and provide a unique very long number as reference. When calling the webpage it shall be possible to use the ID (as part of the URL) to consider with above functionality only the files as selected by reference ID). Note, this is not a shopping card. It is much simpler. Details on functionality and style up on contracted project. Expect some review rounds. IM contact to programmer while coding requested. On Design: Very reduced style, but looking worthy, not cheap!. (Whiteish style, white background, grey and black colors). Effects shall be stylish but small. I.e. simple effects where appropriated. The look and feel shall be stylish and for a designer / photographer appealing. Interactive feeling (AJAX) not like a static web page. Programming: It think the overall effort above is quite limited. For all of the above functions web snippet/ free js libraries exists. But it requires an experienced web programmer to put them together. The programmer must show high quality prior work / projects done. If you see any big issue with one of the features let me know, maybe I can come up with an alternative. Coding: JavaScript, JQuery, HTML and CSS. Avoid PHP if possible. Server side can be via CGI. Let me know if some other coding languages are more meaningful. No SQL or similar needed. Webpage / Scripts must be clearly structured with comments for later extension of source code. Webpage shall work across all major browsers versions of IE, FF, Safari. The design must be based on CSS. Must allow later customization of e.g. webpage layout, grid, some effects. Design must allow to embed the page in a framework (e.g. existing webpage layout, or similar) As much as possible parameters must be configurable via simple config file on server (from within the folder viewed). Must have config parameters are: grid layout, info shown together with thumbnail grid, pictures per page, thumb size, mid-size, selection possible (y/n), PDF allowed (y/n), ZIP allowed (y/n), single original file download (y/n), lightbox options, related to layout and effects (y/n). Rights: The software must be based only on open-source, freeware scripts. Show reference in code. Avoid GPL or alike (request prior). Upon completion all rights on the Product including Design and source code shall be transferred to the buyer (me) for any kind of further use and development.
