This module looks great but I am having trouble getting it to work with 8.0(trunk). I think there must be some difference in how the http library works.

did you succeed to place multi images in the same product on odoo v8?

@Grayson,

I'd recommend taking a look at the progress of the OCA's port of product_images to 8.0. Pedro Baeza has added a number of new useful features to it, and it looks almost complete:
https://github.com/OCA/product-attribute/issues/42
While it installs in 8.0, I would not recommend using it in production, as it is a development branch. I believe that it's pretty close to being pushed to stable though if you're interested at testing out the new features.

As always back up your database/filesystem first before installing. When I installed the module I noticed that it over-rides the default product image field. It leaves whatever images were stored in that field and simply uses the first image in whatever set of multiple images you upload using the module.

Be aware that once you uninstall the module any images that you uploaded with the multi image module will be removed.

I put together a module for storing multiple product images based on product_images from 7.0, and then built a view to display them in synced sliders on the product page as most people are used to in e-commerce platforms here:

In case you're interested in displaying them on the frontend/webshop as well.
