I have already developed an admin panel where admin uploads a pdf file (and/or separate images), selects an area inside each page (image) with an ajax marquee tool and inserts url/link in a specific part of a specific page. There could be many links in separate parts of a specific page of an online catalogue. The user side of this thing is in flash mode. I need it done with ajax.
You can make it look like this: [url removed, login to view] having the thumbnailing/navigation features and the rest effects/transitions.
Take a close look at this: When user rolls over the specific part of the catalogue's page having a link, it gets highlighted with some color around this part. Of course you should try to change the layout a little bit. I don't want this website to accuse me of copying it.
You should also fix something in my admin panel: while trying to upload big PDF files (larger than 20-30mbs) an error occurs and script does not allow me to upload big files. It is not a server side problem (i have searched about it). It is apparently a script's problem.
