Multiple insert transaction for image uploads

Hello !
I can't figure it out how to connect multiple insert transactions on one page?
For example - I want to upload images from page with different categories(have menu list) and insert by the one button all the images at once.

image 1, cat 1
image 2, cat 2
image 3, cat 3

button to insert

Any Ideas? Where to start from?
Thanks, Nick.

Please help ! Maybe link for some tutorials?
